We present a wavelength locking platform enabling the feedback control of silicon (Si) microring resonators (MRRs) for the realization of a 4 × 10 Gb/s wavelength-division-multiplexing (WDM) transmitter. Four thermally tunable Si MRRs are employed to multiplex the signals generated by four directly modulated lasers (DMLs) operating in the L-band, as well as to improve the quality of the DMLs signals...
We propose an novel ultra-dense, low-loss optical coupling solution with optimized coupler design for silicon photonics chip, which is a key enabling technology for optical chip scale package with 336 channels.
Optical chip scale package is a key transceiver technology for future communication networks. A novel scheme is proposed with 336 electrical and optical channels integrated on single substrate. A novel ultra-dense optical IO solution for silicon photonics chips is proposed as an important enabling technology.
We present a control system for wavelength stabilization of silicon MRR used to improve ER in a four-channel DML-based transmitter. The ER enhancement is achieved with automatic control and the sensitivity of the system is better than −28 dBm at 10−3 BER after 40-km transmission.
An ultra-dense optical IO solution for silicon photonic chip is proposed, based on multi-core fiber array and three dimensional optical interposer. We demonstrate an 84-channel prototype with 3.5mm width on optical coupling interface.
