Abstract
A device that compensates for focal point drift of transmitted optical beams caused by ambient temperature changes by using a position adjuster to adjust the alignment of channels of a target planar lightwave circuit ('PLC'). The channels of the target PLC may taper open. In one implementation, the device may also use a birefringence plate to compensate for polarization dependent focal point drift.
