In a world concerned with saving energy, the use of GaN-based solid-state lighting sources has gained interest for visible light communications (VLC), where a light-emitting diode (LED) or laser diode can be exploited, not only to provide illumination, but also communication simultaneously. Contemporary applications are expanding to include underwater and optical fiber communications, as well as the traditional free space domain. It has been shown that micro-LEDs have high modulation bandwidths [1] and can achieve fast data transmission rates, in particular by exploiting higher modulation techniques [2]. However, their performance is limited by the material carrier lifetime and hence laser diodes are considered to further this work. The laser diodes used in this work can give powers of up to 50-100 mW and emit at wavelengths between 421-429 nm. The frequency response of these devices was measured, with maximum -3 dB bandwidths in excess of 2 GHz acquired. One of these devices was used to conduct data transmission experiments in free space, and eye diagrams were achieved without any pre- or post-amplification at data rates up to 2.5 Gbit/s [3]. Error-free data transmission was confirmed by conducting bit-error rate measurements using a pseudo-random bit sequence (PRBS) of 27-1 bits in length. However, further tests showed that data rates of 3.4 Gbit/s could be achieved. These are the fastest transmission rates achieved from a directly modulated laser diode without any higher order modulation schemes. These results not only show the potential of GaN laser diodes for high-speed free-space VLC over short distances but also their potential for use in fiber. High speed measurements were conducted through varying lengths of step-index plastic optical fiber (SI-POF). A different laser (from the same batch), emitting at a wavelength of 429 nm was used to conduct frequency response measurements through the fiber. Fiber lengths of 1 m, 2.5 m, 5 m and 10 m were tested in order to see the trend of bandwidth against fiber length. This device had a -3 dB bandwidth of 1.71 GHz in free space and could achieve error-free data transmission at 2.5 Gbit/s, like before. The maximum bandwidth values achieved for 1 m, 2.5 m, 5 m and 10 m of fiber were 1.68 GHz, 1.63 GHz, 1.62 MHz, and 1.1 GHz, respectively. This can be seen in Figure 1 (a).","PeriodicalId":349795,"journal":{"name":"2015 IEEE Summer Topicals Meeting Series (SUM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131343771","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}

Lasers can be directly modulated at rates as high as 50GHz, much faster than a typical solid state LED that is limited by spontaneous emission to <;1GHz. Unfortunately, lasers have a severe scaling problem; they require large cavities operated at high power to achieve efficient lasing, making on-chip integration a serious challenge. A properly designed LED, on the other hand, can be made arbitrarily small and still operate with high-efficiency. Recent work has shown that the quantum yield and spontaneous emission rate of nanoemitters can be drastically increased by coupling to an optical antenna. In this talk, I will demonstrate that by utilizing proper antenna design, an optical antenna coupled to a semiconductor nanoLED can be created that is faster than a laser while still operating at >50% efficiency. The use of circuit models for antenna design and recent experimental work coupling semiconductor emitters to optical antennas will be discussed.","PeriodicalId":349795,"journal":{"name":"2015 IEEE Summer Topicals Meeting Series (SUM)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114399953","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}

Negative curvature fibers have drawn a lot of attention for mid-infrared (IR) transmission. An antiresonant reflecting structure is used to confine the light in the negative curvature fiber. Prior research studied the effects of tube number, tube glass thickness, boundary curvature, and gap distances between tubes. In the paper to be presented at the 2015 IEEE Topicals Meeting, we use numerical simulation to find the parameters that yield low leakage loss for the chalcogenide negative curvature fiber. We report that the optimal glass wall thickness calculated from the numerical simulations is slightly larger than the glass wall thickness corresponding to the antiresonance condition from analytical predictions. Increasing the glass wall thickness by 0.05 mum yields accurate empirical design outcomes in the chalcogenide negative curvature fibers with the parameter ranges we consider in this paper. Our research will help other researchers to quickly identify the optical glass tube wall thickness when fibers are drawn.","PeriodicalId":349795,"journal":{"name":"2015 IEEE Summer Topicals Meeting Series (SUM)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122010772","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}
