The polarization compositions of fundamental quasi-TE and quasi-TM modes of a strip silicon waveguide are characterized with free-space polarizers, and their polarization extinction ratios depend on the sizes of various apertures in the experimental setups.
We demonstrate a scheme to scale the bandwidth of a frequency comb generated by phase modulation of CW lasers using four-wave mixing in a silicon nano-waveguides, resulting in >100 comb lines spaced by 10-GHz within 5-dB bandwidth.
We evaluate the optical communication performance of individual comb lines generated in silicon nitride microresonators. A high coherence mode yields error-free communications at 10 Gb/s, while a partially coherent mode results in closed eye diagrams.
An optical diode transmits forward 10Gbps data with less than 0.5dB power penalty, while suppressing and distorting backward data with a 11dB nominal power penalty. The nonreciprocal transmission is also demonstrated with a silicon modulator.
A compact and high extinction SOI polarization rotator is fabricated and characterized. For TM to TE rotation, a device 37.5μm in length is demonstrated to have a polarization extinction ratio between 17.8–26dB from 1525nm to 1570nm.
A completely on-chip solution for radio-frequency arbitrary waveform generation (RFAWG) is proposed with silicon add-drop microring resonators and tunable all-pass microring delay lines. Preliminary results are shown for the pulse shaping effect.
