In this paper we address silicon photonics based optical transceiver technology for applications in advanced data communications such as high performance computing and hyperscale datacenters.
We demonstrate two 1Tbit/s superchannel architectures using a compact, FSR-tunable gain-switched comb source. SSMF transmission of 18GBaud Nyquist-WDM shaped PDM-QPSK and PDM-16QAM modulation is reported, with a capacity up to 1.296Tbit/s and SE of 7.2bit/s/Hz.
The authors investigate and compare the performance of three different optical frequency comb sources in an intensity modulated and directly detected compatible SSB OFDM system. The influence of relative intensity noise and carrier-to-noise ratio of the different multicarrier sources, on the performance of a 12.5 Gb/s compatible SSB OFDM system, were investigated experimentally and by simulation....
