When using holographic memory as electrical memory, a photodiode array is frequently used to convert diffracted light from the holographic memory to electrical signals. However, when using lasers of various wavelengths to read multiple contexts, although the light of each laser has different diffraction limitations, the photodiode array resolution must be designed based on the longest wavelength laser's light diffraction limitation. The proposed technique achieved the best recording density for a 2D holographic memory for lasers of every wavelength by adjusting the recording region size of the holographic memory for each context to satisfy the resolution of the photodiode array.","PeriodicalId":6758,"journal":{"name":"2020 IEEE 8th International Conference on Photonics (ICP)","volume":"12 1","pages":"86-88"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79136560","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}

SoC has the capability to reduce complexity and increase the flexibility in the design of digital instruments. Experimental results show that the system can regulate the period and Duty cycle for two output waveforms and frequency. The employment of SoC in the TDM-FBG sensor system provides overall performance enhancement over the conventional single pulse, since it shows a rapid response time of 3.4 ns compared to 8.2 ns when Arbitrary Waveform Generator is used. Further enhancement on accuracy can be done by using a high-speed digital-analog converter board with a higher sampling rate.","PeriodicalId":6758,"journal":{"name":"2020 IEEE 8th International Conference on Photonics (ICP)","volume":"1 1","pages":"80-81"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88416761","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}

In this paper, we propose a new RoF-VLC system using 10km fiber and multiple LEDs for indoor VLC through simulation. Gray coded input sequence with either On-Off Keying (OOK) or 16 QAM-OFDM modulated was used for data transmission. Radio signals transmit 1.5 Gb/s and 2.5 Gb/s data using OOK and16 QAM-OFDM, respectively. The signal from the 10 km fiber is sent to an access point with red, green, blue and yellow (RGBY) LEDs each with ~50 MHz modulation bandwidth. Filters such as Gaussian, Bessel, Trapezoidal, and Rectangle are used to increase the modulation bandwidth of LEDs. The maximum data rates that can be achieved at the VLC receiver is 400 Mb/s and 3.2 Gb/s using OOK and 16QAM-OFDM, respectively. The effect of filters and beam convergence on BER is also measured in this paper. Beam convergence is important for short range applications. The results obtained using the RoF-Vlcproposed in this paper are better compared to the ones in previous works in this area.","PeriodicalId":6758,"journal":{"name":"2020 IEEE 8th International Conference on Photonics (ICP)","volume":"14 1","pages":"84-85"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82013389","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}

The large evanescent field of tapered fiber allows $mathrm{MoWS}_{2}-mathrm{rGO}$ coated tapered fiber to absorb the surrounding heat and changes the refractive index of $mathrm{MoWS}_{2}-mathrm{rGO}$ coated tapered fiber. The refractive index change is due to thermo-optic effect. When there is a change of surrounding temperature, the refractive index of the coated tapered fiber changes and this subsequently alters the incident light polarization. The sensitivity of the proposed temperature sensor is measured at 0.63°/°C.
