01:30-01:45
2017-10-02 01:30 2017-10-02 01:45 America/Denver Low-Dark Current III-V Photodiodes Grown on Silicon Substrate InAlGaAs/InP p-i-n photodiodes epitaxially grown on silicon substrate with a dark current density as low as 1.3 mA/cm2 at -3 V are demonstrated. Responsivity, bandwidth, and output power at 1-dB compression are 0.76 A/W, 8 GHz, and -3.4 dBm, respectively. Hilton Santa Fe Historic Plaza Salon I

110 GHz Zero-bias Based UTC-PD for Radio-over-fiber Transmission Through Multicore Fiber
01:45-02:00
2017-10-02 01:45 2017-10-02 02:00 America/Denver 110 GHz Zero-bias Based UTC-PD for Radio-over-fiber Transmission Through Multicore Fiber We developed a zero-bias operational UTC-PD, which exhibited wide bandwidth over 110 GHz. The photoreceiver was demonstrated for high-data-rate (12 Gbps, OFDM, 16-QAM) radio-over-fiber transmission through multicore fiber. BER ≦ 1×10-3 without crosstalk from outer cores could be confirmed. Hilton Santa Fe Historic Plaza Salon I

Temperature dependence of nonlinearity in high-speed, high-power photodetectors
02:00-02:15
2017-10-02 02:00 2017-10-02 02:15 America/Denver Temperature dependence of nonlinearity in high-speed, high-power photodetectors We present an experimental study of the nonlinearity of modified uni-traveling carrier (MUTC) photodiodes at cryogenic temperatures. At 120 K, the amplitude-to-phase (AM-to-PM) conversion nonlinearity is reduced by up to 10 dB, resulting in nearly 40 dB AM-to-PM rejection over a broad photocurrent range.

Microring Weight Bank Designs with Improved Channel Density and Tolerance
02:15-02:30
2017-10-02 02:15 2017-10-02 02:30 America/Denver Microring Weight Bank Designs with Improved Channel Density and Tolerance Microring weight banks enable reconfiguration in analog photonic networks and multi-channel RF front-ends. We demonstrate 2-ring weight banks and show that they are tolerant to fabrication and thermal effects. Weights consisting of two microrings can potentially increase channel capacity by a factor of 2.72-fold. Hilton Santa Fe Historic Plaza Salon I
