Abstract

A bulk optic (de)multiplexer (10) consists of a fiber pigtail array (20), a focusing optic (18) and a wavelength dispersive element or grating (16) in optical alignment along an optical axis (22). The focusing optic is rigidly affixed to the frame and the fiber pigtail array (20) and wavelength dispersive element (16) are attached by adjustable connectors (112, 56, 340) to facilitate al ignment. The frame (12) has thermally expansive elements to compensate for shifts in light beams processed by the (de)multiplexer as a function of temperature. Vibration dampers (150, 152, 154, 160, 200) isolate the frame and optical elements form vibrations applied to the (de)multiplexer.
