HEATED INTEGRATED OPTICAL DEVICE PACKAGE

摘要

An integrated optical package comprises an integrated optical device, a pair of planar heaters disposed on either side of the device, the heaters being separated from the device by a fluid gap. This can be provided within a supporting structure comprising a base part and a lid part, the base part having a hollowed region in which is disposed one heater and a ledge surrounding the hollowed region in which the device is supported, the lid having an interior surface carrying the second heater. The arrangement allows for greater thermal stability, particularly in the presence of air flows. The fluid gap is preferably less that 3mm, more preferably 2mm or less. The fluid gap is also a suitable location for a thermistor for regulating the heater output.
