Title: High efficiency insulation for improving thermal efficiency of bubble optical switch
Inventor: NYSTROM MICHAEL
IPC: B81B1/00
Filed: 2002-04-25
Abstract: PROBLEM TO BE SOLVED: To provide optical switches which prevent heat leakage between a core and a fluid reservoir and is prevented of the infiltration of atmospheric gas. SOLUTION: The optical switches (10 and 10') include a core (12), the fluid reservoir connected via a pipe (16) to the core (12), a heat-countermeasure device (18) and thermal insulation structures (32 and 32'). The core (12) includes a base (20), a matrix control substrate (22) and a planar waveguide circuit (24). The planar waveguide circuit (24) has a plurality of waveguides (26) and trenches (3) to change the route of optical flow. The fluid reservoir (14) supplies fluid to a plurality of the trenches (30) of the core (12). The core (12) and the fluid reservoir (14) are attached to the heat countermeasure device (18) and heat-countermeasure device (18) removes heat from the core (12) and supplies some of the heat to the fluid reservoir (14), thereby maintaining the fluid reservoir (14) at a temperature higher than the temperature of the core (12).  The thermal insulation structures (32 and 32') reduce the leakage of all the heat from the fluid reservoir (14) to the core (12). The thermal insulation structures (32 and 32') improves the temperature distribution and overall temperature of the planar waveguide circuit (24) and prevent the unwanted infiltration of the atmosphere gas to the optical switches (10 and 10').
