Many properties of an optically interconnected system can be improved through the use of a modelocked laser. The short pulse duration, high peak power, wide spectral bandwidth, and low timing jitter of such a laser lead to these benefits. Timing advantages include simplified synchronization across large chip areas, receiver latency reduction, and data resynchronization. Lower power dissipation ...

We report on a simple bidirectional optical link using two InP-based Fabry–Pérot (FP) lasers operating at 1.55μm wavelength as optical transmitter and receiver. Since the emitted light of one FP laser is absorbed by the other when it is reverse biased, no additional photodiode is required. The optoelectronic devices are butt-coupled to single-mode fibers (SMFs). With this configuration, up to 1...
