Compact and Athermal DQPSK Demodulator with Silica-Based Planar Lightwave Circuit
We present a full description of a polarizationindependent athermal differential quadrature phase shift keying (DQPSK) demodulator that employs silica-based planar lightwave circuit (PLC) technology. Silica-based PLC DQPSK demodulator has good characteristics including low polarization dependence, mass producibility, etc. However delay line interferometer (DLI) of demodulator had the large temp...
متن کاملProposal for fabrication-tolerant SOI polarization splitter-rotator based on cascaded MMI couplers and an assisted bi-level taper.
A novel silicon-on-insulator (SOI) polarization splitter-rotator (PSR) with a large fabrication tolerance is proposed based on cascaded multimode interference (MMI) couplers and an assisted mode-evolution taper. The tapers are designed to adiabatically convert the input TM(0) mode into the TE(1) mode, which will output as the TE(0) mode after processed by the subsequent MMI mode converter, 90-d...

Mday, M arch 24 transmission system was 20 Gb/s, while the symbol rate was 10 Gbaud (=10 GS/s). The second MZ modulator was used as a pulse carver to generate RZ-DQPSK signals. For the 20-Gb/s DQPSK receivers, two 100-ps DIs with two separate balanced receivers are generally required to simultaneously demodulate the two 10-Gb/s data streams contained in the 10-Gbaud DQPSK signal [4]. However, w...
متن کاملSigned chromatic dispersion monitoring of 100Gbit/s CS-RZ DQPSK signal by evaluating the asymmetry ratio of delay tap sampling.
In this paper, we theoretically and experimentally demonstrated the residual chromatic dispersion (CD) monitoring of 100-Gbit/s carrier suppress return-to-zero differential quadrature phase shift keying (CS-RZ DQPSK) signals by evaluating the asymmetry ratio of delay tap asynchronous sampling. This scheme can easily differentiate the positive and negative residual CD of the fiber link. The reso...

We propose a bidirectional wavelength division multiplexing passive optical network (WDM-PON) based on a reflective semiconductor optical amplifier (RSOA) by employing a differential quadrature phase shift keying (DQPSK) signal for down-link and an on-off keying (OOK) re-modulated signal for up-link over 45km SMF colorless WDM-PON without dispersion compensation was demonstrated for both 10 Gbi...
