Abstract
In this letter, we describe the use of direct optical injection locking of a self-oscillating InGaAs-InP heterojunction bipolar phototransistor to extract the clock of high-speed optical signals. We demonstrate a single MGM oscillator, which can be locked by 10- to 40-Gb/s return-to-zero signals with high efficiency and low noise.Keywords
