Brazed bonding of optical glass fiber and silicon substrate.

摘要

A device is provided having an optical glass fibre (16) bonded to a silicon substrate (2) via a brazed bond (18). The bond completely seals the fibre (16) within an alignment groove (8). A cover (not shown) is provided such that the device can be evacuated. The brazed bond does not outgas and hence a high vacuum can be maintained within the device. The brazing alloy comprises at least one of titanium, zirconium, chromium, aluminium and vanadium.
