Design and realisation of a MZI type polymer based high speed EO-modulator

We designed a 20 GHz Mach Zehnder interferometric EO-modulator based on a new developed polyesterimide. Measurements show a V/sub /spl pi// of 7.5 V, an insertion loss of 11 dB and an extinction ratio exceeding 20 dB for an interaction length of 2 cm

SECOND HARMONIC GENERATION FROM ORGANIC OPTICAL WAVEGUIDES ON DIFFRACTION GRATINGS

We present experimental results of second harmonic generation using a waveguide of PUSC deposited on a silver diffraction grating. The reflected second harmonic signal is enhanced at the angles of resonant excitation of the guided modes or of the surface plasmon. At these angles, we observe unexpected minima in the second harmonic signal, when the second harmonic frequency is situated within the absorption range of PUSC
