III-V semiconductor compounds tend to exhibit strong nonlinearities; these typically come along with undesirable effects such as nonlinear absorption. In quaternary III-V compounds, one has a good control over this characteristic. For instance, by shifting the band-gap wavelength through adjusting the material composition, one can change the range of wavelengths that can experience two-photon absorption. Therefore, it would be possible to minimize the losses due to nonlinear absorption [1]. Based on the possible band-gap wavelength and refractive index ranges that can be achieved in these two compounds, one can expect that both InGaAsP and AlGaAsSb waveguides can be suitable for wide-range wavelength conversion. InGaAsP waveguides can, for example, be co-integrated with InGaAsP laser sources to extend their operation ranges to longer wavelengths (2 μm and beyond). The properties of AlGaAsSb, on the other hand, allow passive waveguide devices operating in the Telecom C-band.","PeriodicalId":153736,"journal":{"name":"2017 Photonics North (PN)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114225802","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}

Incorporation of mirrors and cavities into hollow-waveguides could further enhance these functionalities, by introducing 3-dimensional (3-D) confinement options. It is challenging to implement conventional axial reflectors (e.g. Bragg gratings, photonic crystals) within hollow-core waveguides [2]. Here, we describe an alternative method that employs mode cut-off sections as axial reflectors; these cut-off sections can be used as mirrors in the formation of 3-D hollow-waveguide-based microcavities. We furthermore show that a thin film buckling process [3] provides a straightforward means to fabricate the proposed structures.","PeriodicalId":153736,"journal":{"name":"2017 Photonics North (PN)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127025881","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}

Inherent modal dynamics allow facile manipulation of resonant amplitudes, phase, polarization, and spectral bandwidth. This enables design of robust devices with minimal layer count.
