Abstract: A hybrid four layer guide (FLG) including a glass guide and a 2-docosylamino-5-nitropyridine Langmuir-Blodgett film is described, and some tests are reported on an electro-optic modulator based on this FLG. The modulation of laser diode light was obtained by guided mode interference, without a Mach-Zehnder configuration of the device. From the modulated signal the r22 electro-optic coefficient was calculated as 11 pm/V.
