A free-space RTD emitter operating at 353GHz is described. The fabrication process consists of a dual-pass I-line photolithography & etch technique using an air bridge, allowing low resistivity ohmic contacts, and accurate control of desired device area. With extrinsic circuit elements taken into account, the intrinsic semiconductor efficiency is analysed to investigate structural improvements for radiative efficiency. Such optimised structures are presented, and then characterised after being epitaxially grown with commercially viable metal-organic vapour phase epitaxy (MOVPE) reactors. A combination of low temperature photoluminescence spectroscopy, X-Ray diffractometry, and transmission electron microscopy attest the quality of the new material. We end with a suggestion for the next steps to exceed technological readiness levels of 8, and use monolithic RTD emitters as components in new systems.","PeriodicalId":145258,"journal":{"name":"2018 IEEE British and Irish Conference on Optics and Photonics (BICOP)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122900000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We describe the environment representation model used, the Stixel World, and its benefits for compact scene representation. We show our preliminary results of its application in a diverse environment and the limitations reached in our experiments using imaging systems. We argue that this method has been developed in an ideal scenario and does not generalise well to uncommon changes in the environment. We also found that this method is sensitive to the quality of the stereo rectification and the calibration of the optics, among other parameters, which makes it time-consuming and delicate to prepare in real-time applications. We think that pixel-wise semantic segmentation techniques can address some of the shortcomings of the concept presented in a theoretical discussion.","PeriodicalId":145258,"journal":{"name":"2018 IEEE British and Irish Conference on Optics and Photonics (BICOP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129162187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It goes on to outline the significance of these effects and the situations in which single-event effects can occur, followed by a summary of current testing and characterisation practices for determining the sensitivity of components to such events. Finally, the use of a relatively new technique for SEE testing, employing a pulsed laser, is introduced and examples quoted where such a technique has delivered benefits compared to more established methods. Laser testing promises to deliver much faster and lower cost results, opening up access to SEE testing to a wider range of users than is currently the case.","PeriodicalId":145258,"journal":{"name":"2018 IEEE British and Irish Conference on Optics and Photonics (BICOP)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124420166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It becomes more complicated if the connection is assumed to be dynamic in nature. In this paper for the dynamic (increase) connection, the probability density function of unused and used optical band is calculated. The role of smaller unused frequency slots on the spectral utilization is extensively analyzed through simulation. We propose a quantitative metric to quantify the fragmentation in a link. On the basis of metric, we propose a routing and spectral algorithm called Fragmentation suppressed RSA (FS-RSA). Our proposed FS-RSA helps in accommodating more number of connection by decreasing the fragmentation as compared to the conventional First fit and Random fit. The proposed scheme takes lesser computational time as compared to MinEnt RSA.","PeriodicalId":145258,"journal":{"name":"2018 IEEE British and Irish Conference on Optics and Photonics (BICOP)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129283427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasound link is employed by the external device to power the implant and communicate data at 300 KHz radial resonances frequency. The wireless data transmission link is represented by two off-chip piezoelectric transducers of tube shape and dimensions (OD:3.5, ID:2.5, H:3) mm with 300 KHz radial resonances frequency.

Recent advances in single-photon avalanche diode (SPAD) arrays provide image sensors capable of single photon counting imaging. Such devices provides camera systems which can operate under low illumination levels and high frame rates, with fully digital in-pixel processing capabilities. Here, we present a hyperspectral imaging system based on low level illumination of a target scene using nine LEDs, each with different emission wavelengths. The backscattered light is captured by a SPAD camera, which can recover spectral information based on the number of photon counts received for each illumination wavelength.","PeriodicalId":145258,"journal":{"name":"2018 IEEE British and Irish Conference on Optics and Photonics (BICOP)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131722984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, typically non-linear effects are weak; a typical non-linear index change is on the order of 0.01% or less and therefore they typically require high-power, short-pulse lasers, as well as long interaction length or resonant enhancement. Here, we show that a thin metasurface (50 nm total thickness), consisting of metal antennas on an epsilon-near-zero (ENZ) film, can produce a giant non-linear response with the refractive index change, ∆n, exceeding 2 across a broad spectral range in the near-infrared, including the commercially important C and L band regions.","PeriodicalId":145258,"journal":{"name":"2018 IEEE British and Irish Conference on Optics and Photonics (BICOP)","volume":"21 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133425188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
