We review recent advances of using liquid crystal on Silicon based WSS technology for advanced functionality in communication systems such as an all-optical DFT filters for multiplexing and demultiplexing optical OFDM signals.
In this paper, we experimentally demonstrate a single-band self-coherent polarization-multiplexed optical orthogonal frequency-division multiplex system with a raw data rate of 120 Gbit/s. The transmitter uses a novel RF structure that eliminates the need for RF mixers and optical filters. The receiver uses a novel architecture where the optical carrier is filtered and amplified for self-coherent...
We experimentally demonstrate a single-band direct-detection polmux OFDM system using novel colorless transmitter and pol-mux receiver architectures. We transmit 100 Gbit/s over 500 km of standard SMF with a spectral efficiency of 3.57 bit/s/Hz.
We experimentally demonstrate a novel colorless transmitter for direct-detection optical OFDM that requires lower sample-rate DACs than previous designs, without RF mixers. We transmit 24-Gbit/s over 800-km SSMF using two 10 GS/s DACs.
