Optical waveguides with power monitoring or optical detection capabilities are disclosed. The waveguide includes a lower cladding, a core disposed on the lower cladding, an upper cladding disposed on the core and a trench extending transversely through a distal end of the lower cladding, core and upper cladding. The trench includes a distal wall that provides a reflective surface disposed at an angle relative to the end of the core of greater than 90&#xb0;. A detector is disposed above the trench for receiving a reflected light beam off of the reflective surface. Various methods of manufacturing these devices are also disclosed.

Waveguides with optical monitoring

Thermal optical switch apparatus with enhanced thermal isolation includes a cladding region with first and second spaced apart waveguide cores buried therein to form first and second waveguides. A thermal insulation barrier filled with insulating material is formed in the cladding between the first and second waveguides to thermally isolate the waveguides. In one embodiment, the insulating material is an aerogel. Methods of operation are also described.
