  • Temperature-independent optical coupler
    Patent number: 5307429
    Abstract: An optical coupler 13 comprises a monolithic block of transparent optical material with a pair of opposite sides configured so that an optical signal can be transmitted between a first device 12 and a second device 14 with internal reflections within the coupler 13. Because the optical coupler 13 is monolithic, thermal expansions and contractions in response to extreme fluctuations are uniformly distributed throughout the coupler 13 and therefore do not significantly distort the optical signal.
