Abstract
Forced oscillation based on self-injection locked phase-locked (SILPLL) optoelectronic oscillator (OEO) technique is the basis of highly stable and low phase noise oscillators to be used as a key component in modern communication and sensing systems. To avoid large-size modular OEO, inter-modal oscillation at X-band frequencies is achieved in a compact multi-mode multi-section semiconductor laser using InP foundry service. Self-forced oscillation technique of SILPLL is demonstrated, where a phase noise performance of -98 dBc/Hz is measured at 10 kHz offset carrier of 11 GHz, which is an improvement of 68 dB compared with the free-running condition, which corresponds with 6(X) times reduction in calculated timing jitters from the free-running case to reach 0.45 ps fig over 1 kHz to 1 MHz bandwidth.
