A collimator device and a collimator lens array for an optical circuit switch are provided. The collimator includes a fiber array including multiple optical fibers disposed in a hole array. An optical lens array is aligned and coupled to the fiber array. A spacer is disposed between the fiber array and the optical lens array and provides substantially uniform spacing between lenses in the optical lens array and corresponding fibers in the fiber array. Multiple pads are positioned along edges of a surface of the spacer facing the optical lens array defining a first separation gap between the spacer and the optical lens array. A first epoxy bonds the spacer to the optical lens array, and a second epoxy bonds the spacer to the fiber array. The optical lens array includes a glass substrate having a first surface defining lenses in a two-dimensional array.

A demultiplexer/multiplexer is disclosed wherein an arrayed waveguide grating having a reflector at an end includes selectable signal path blockers. The arrayed waveguide device has a common input/output port for launching radiation in the form of an input signal having n wavelengths therein and for receiving back via the reflector at the input/output port a selected channel of the input signal. In operation a multiplexed signal have n channels is launched therein and a selected channel is output for analysis or further processing.

An optical amplifier comprises a device substrate, a first waveguide embedded in the device substrate, a plurality of pumping waveguides coupled along interspersed portions of the first waveguide, and a plurality of lasers. The lasers are positioned to provide pumping light beams into the pumping waveguides.
