Abstract :
Transverse magnetic (TM) mode selective polymer Mach-Zehnder modulators with self-aligned electrodes were fabricated for the first time in the electro-optic polymer material APC-CPW1 by employing a poling-induced (PI) writing method. The waveguides support only a TM polarisation, when an arbitrarily polarised optical source is incident. Modulators with a single 3 cm long driving electrode show a Vπ of 3.5 V at 1.55 μm.
