Low power silicon photonic transceivers

We present ultra low power silicon photonic transceivers, including a 320 fJ/bit reverse biased ring modulator integrated with CMOS driver, and a 690 fJ/bit record-low power receiver with sensitivity of -18.9 dBm at 5 Gbps for bit-error-rate of …

Circuits for silicon photonics on a “macrochip”

Recent advances in silicon photonics bring significant benefits to "macrochip" grids made of arrayed chips. Such configurations have global interconnects long enough to benefit from the high speed, low energy, and high bandwidth density of optics. In …
