A Consolidated Multi-rate Burst-Mode DPSK Transmitter Using a Single Mach-Zehnder Modulator
Phase modulation Free-space optical comm Optical communications
2015/5/26
We demonstrate phase modulation, pulse carving, and burst-mode windowing in a single Mach-Zehnder modulator, significantly reducing size, weight, power, and complexity of prior three-modulator designs...
Digital multi-rate receiver for 10GE-PON and GE-PON coexistence
GE-PON multi-rate receiver
2015/5/18
We demonstrate an NRZ multi-rate digital receiver capable of receiving upstream TDM traffic line-rates from GE-PON to 10GE-PON, that utilizes a simple optical front end and polyphase DSP at 2 samples ...
Multi Data-Rate Synchronization of 40 GHz Mode-Locked Quantum-Dash Lasers Diodes
Mode-Locked Lasers Diodes Quantum-Dash Multi Data-Rate Synchronization
2015/5/15
Beat-tones at 40-GHz from a QDash-ML laser under 10 to 160 Gb/s optical injection are analyzed. A FWHM linewidth less than 8 Hz is obtained regardless of the rate of injected data stream.
Bit-Rate-Variable and Order-Switchable Optical Multiplexing of 160- Gbit/s PRBS Data Using Tunable Optical Delays
Bit-Rate-Variable Order-Switchable Optical Multiplexing PRBS Tunable Optical Delays
2015/7/15
We experimentally demonstrate 160-Gbit/s PRBS data multiplexing with tunable rate and order using switchable optical delays and conversion/dispersion based tunable optical delay. Less than 9 dB penalt...
Data Rate Enhancement of RSOA-based WDM PON Systems using Feed-forward Equalizer and Forward Error Correction
WDM PON Systems Feed-forward Equalizer
2015/8/6
Effect of FFE and FEC to enhance the data rate of RSOA was investigated. 4.75Gbit/s was achieved by 0.6GHz RSOA using 4-tap FFE and ~14% FEC.
A Bit-Rate-Transparent Monolithically Integrated Wavelength Converter
Bit-Rate-Transparent Monolithically Integrated Wavelength Converter
2015/7/30
We demonstrate a monolithic wavelength converter based on a PD-EAM optical gate and tunable SGDBR laser operating at any bit rate up to 40 Gb/s in both NRZ and RZ formats.
