0.18-microm complementary metal-oxide semiconductor push-pull vertical-cavity surface-emitting laser driver operating at 2.5 Gb/s with symmetric rising and falling edges.

A vertical-cavity surface-emitting laser (VCSEL) driver design that utilizes a novel push-pull circuit topology is described. The VCSEL driver design can provide both a current pushing and a current pulling mechanism and therefore is capable of producing symmetric rise and fall times. The design was implemented in a 0.18-microm foundry n-well complementary metal-oxide semiconductor technology and operates at data rates up to 2.5 Gb/s with a power consumption of 45 mW at an average optical output power of 1 mW.

Experimental techniques using optically enabled ring oscillators.

We present a method for characterizing transceiver performance in parallel optical data links. By establishing a bidirectional link between two optically enabled chips, the conditions for a ring oscillator are made possible. We propose this technique as a means of measuring the sensitivity of transceiver latency to controlled variables such as temperature, optical output power, supply voltage, and device misalignment. This method is noninvasive and independent of the packaging, circuit topology, and optical medium used. The technique is demonstrated experimentally, and results are compared with a simulation.
