Linearization of an interferometric modulator at microwave frequencies by polarization mixing
The linearization of all interferometric modulator by polarization mixing over the suboctave frequency range of 3.6 to 5.6 GHz is reported. A traveling-wave modulator fabricated in X-cut LiNbO/sub 3/ utilizing the r/sub 33/ (TE) and r/sub 13/ (TM) electrooptic coefficients was employed. The effective V/sub pi /s (from a 50- Omega source) were 14 and 43 V for the TE and TM modes, respectively. The modulator response was not optimized for this frequency range. A DC voltage was used to separate bias electrodes to adjust the relative TE and TM phase bias. A polarizer was placed between the diode-pumped Nd:YAG laser source, and the modulator to adjust the relative TE and TM optical power. The modulator output was measured with a high-speed photodetector and spectrum analyzer.<>
