摘要： A vertical surface emitting laser having a mesa structure formed with sloping side walls. A passivation layer including at least two sublayers at least partially covers the mesa structure. The at least two sublayers have differing stress components arranged to at least partially counter each other. By making the mesa structure with sloping side walls, the deposition of the passivation layer in such a way as to minimize the net stress of the passivation layer is facilitated. In addition, the mesa structure has a first stack of mirror layers comprising a semiconductor material doped with a first dopant and having first peripheral oxidized portions extending a first distance into said first stack, and a second stack of mirror layers comprising a semiconductor material doped with a second dopant and having second peripheral oxidized portions extending a second distance into said second stack, wherein the first distance is different from the second distance. By controlling the first distance and the second distance appropriately, the internal stress in the mesa structure can be reduced.

摘要： A power monitoring system uses a low loss reflective element to partially split the output laser beams from an array of laser sources, in a parallel configuration, to produce a monitor beams for each laser source. Each of these monitor beams may propagate within the reflective element in a lossless manner under total internal reflection and into one of a plurality of photodiodes that sense an optical characteristic such as output beam intensity, where this sensed signal is then used as part of a feedback control to control operation of the laser sources in the array.

摘要： A photodiode array includes a plurality of monitoring photodiodes capable operating in a voltage mode configuration each able to provide a voltage indicating an intensity of an incident light. Integrated with the monitoring photodiodes is a reference diode configured to produce reference voltages in response to reference currents supplied to that diode. The monitoring photodiodes and the reference diode may be integrated and have the same current-voltage characteristics and the same temperature, for example by fabricating them on the same substrate. The reference diode is supplied with the reference currents in dark manner, meaning without incident light impinging on the reference diode. The resulting reference voltages, the reference source currents, and the measured photo-voltage from the monitoring photodiodes are than used to determine an optical power value at any temperature within the operation temperature range.

摘要： When a high data rate optical signal travels through a fiber link, its high frequency components tend to experience higher losses due to fiber dispersion (modal and/or chromatic). The loss of high frequency components causes the optical eye to close and the sensitivity to degrade. Disclosed is an apparatus and method for an optical transmitter that relies on anti-causal pre-emphasis to counteract the effect of relaxation oscillation, and therefore brings improvements to optical eye symmetry and mask margin (MM).
