Abstract
Mode concentration and propagation constants in Te thin film structures are readily obtained from a transverse resonant method without explicit knowledge of the dispersion relationship from Maxwell's equations. Losses involved, best method of coupling a light beam into a Te thin-film waveguide, non linear Te-X-junctions, bends co and contradirectional coupling, second order harmonic generation (SHG) in a Te Waveguide structure, are briefly discussed. Finally the measured optimized detection characteristics of Te/Si thin film device and the proposed theory of the detection mechanism yield to consider Te thin-films as a potenthlly improved room temperature pulsed C02 laser detector.
