A novel approach to pre-scaled clock recovery in OTDM systems

A new technique for the clock recovery in OTDM transmission systems is demonstrated; it is based on an injected electro-optic hybrid oscillator and offers the advantage of circuit simplicity and frequency scalability. We present a simple, not PLL-based, opto-electronic regenerative circuit, which is based on the electronic frequency divider proposed by Miller and doesn't require components with bandwidth higher than the tributary rate.
