Abstract
The invention is related to an improved mach-zehnder type electro-optic polymer modulator which is capable of controlling its initial output state by post-photobleaching method, thus achieving a more stable output characteristic of a device without use of a bias electrode, which includes first and second electrodes formed on an upper portion of first and second arms have different lengths wherein a mach-zehnder type electro-optic polymer modulator.
Claims1
A mach-zehnder type electro-optic polymer waveguide modulator in which an initial output state can be controlled by post-photobleaching, having two electrodes formed on two arms of the modulator,
- wherein said two electrodes have different length from each other in order to control a initial phase difference between said two arms by using post-photobleaching.
