System Impacts of Modulation Technology and Phase Noise on Coherent Analog Optical Links
Radio frequency photonics
2011/5/22
We describe an analog optical link using amplitude modulation and coherent detection for high SFDR, gain, and low noise figure. We then address the dominant performance-limiting parameters and discuss...
40Gbps,3-bit Operation of a Semiconductor Optical Digital-to-Analog Converter
Semiconductor Optical Digital-to-Analog Converter
2009/7/14
We demonstrate 40Gbps, 3-bit-operation of a semiconductor optical digital-to-analog converter consisting of MMI couplers and delay lines. We achieved output with 7-level amplitude with fixed phase suc...
