摘要： An optical switching device (46; 94; 98) and a method of providing temperature control for the device utilize compensating thermal energy to maintain a consistent operating temperature. The optical switching device may be a thermally activated optical switch that routes optical signals using bubbles that are strategically created along optical paths (58, 60, 62, 64, 66, 68, 70 and 72) within the device. The bubbles are created by thermal energy generated by switching heating elements (84). The compensating thermal energy may be generated by at least one compensating heating element (86A, 86B, 86C and 86D; 100) or by at least one switching heating element that is not currently being used for optical switching, i.e., bubble creation. The compensating thermal energy is varied so that total thermal energy generated by the device is constant, which results in a consistent operating temperature. In a first embodiment, the device includes additional heating elements (86A, 86B, 86C and 86D) that are selectively activated to generate the compensating thermal energy. In a second embodiment, the compensating thermal energy is generated by all of the switching heating elements along one or more optical paths that are in a transmission mode. In a third embodiment, the device includes a single additional heating element (100) that is supplied with a variable electrical power to generate the compensating thermal energy.

摘要： A multistage optical switch includes a stage-to-stage connectivity scheme that provides equalization of losses encountered as optical signals traverse switching crosspoints (30). Each stage (62, 64 and 66) includes more than one switching unit having a first array of input ports (42, 44, 46, 48 and 50) and a second array of output ports (52, 54, 56, 58 and 60) that are selectively coupled by varying the crosspoints between transmissive states and reflective states. The input ports of a particular switching unit and the output ports of the same unit have rankings that are reflective of the number of optical crosspoints that must be traversed by optical signals propagating between input and output ports having the same ranking. High ranking output ports of the switching units of one stage are optically coupled to low ranking input ports of the subsequent stage, thereby defining stage-to-stage optical paths that ensure equalization in the sums of the crosspoints that are traversed when optical signals propagate through the two stages. Preferably, the connectivity of the second stage to a third stage is a mirror image of the connectivity of the first and second stages.

By changing the fluid at the first trench [134-148] to switch the optical switch to cause a light signal to be reflected from the first waveguide [134] into the second waveguide [148] and by partially changing the fluid at the second trench [134-152] to switch the optical switch to cause a portion of the light signal to be reflected from the first waveguide [134] into the test waveguide [152]. The portion of the light signal in the test waveguide [152] can be monitored using a light detector [158].

摘要： A system and method are provided for detection of gas intrusion into a fluid-containing device [50]. The fluid-containing device [50] has a first waveguide [62] and a second waveguide [92] that intersect at a trench [62+92] such that optical coupling between the first and second waveguides [62,92] is dependent upon an absence of a fluid in the trench [62+92]. The fluid containing device [50] includes a fluid removal mechanism for removing fluid to the trench [62+92] to switch the fluid-containing device [50]. An optical connection is made between first ends of the first and second waveguides [62,92] and a light source [102] provides a light at a second end of the first waveguide [62] and a detector [102] detects the light at a second end of the second waveguide [92]. The times required to remove and return the fluid from the trench [62+92] are used as an indicator of gas intrusion into the fluid containing device [50].
