Title: Semiconductor mach-zehnder type optical modulator optical modulator module and optical transmission device
Inventor: IDO TATSUMI
IPC: G02B6/12
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor Mach-Zehnder type optical modulator having stable working point and extinction characteristic even if misalignment arises in an optical coupling system by providing at least part of an optical waveguide with a mode filter which allows the transmission of basic mode light and prohibits the propagation of higher order mode light. SOLUTION: The incident light on the mode filter 1 broader than the optical waveguide 11 spreads to both sides. When this light propagates further, the light is converged to the center and reproduces the light intensity distribution nearly equal to the light intensity distribution of the incident waveform. Namely, the incident light on the mode filter 1 periodically changes its form. This period varies with the basic mode light and the higher order mode light. Then, if the length Lf of the mode filter 1 is set at the period of the basic mode light, the basic mode light has nearly the same intensity distribution in the outlet and inlet of the mode filter 1 and, in the meantime, the light intensity distribution of the higher order mode light is concentrated to the outer side in the outlet of the mode filter 1 and is hardly coupled to the mode of the optical waveguide 11 on the output side of the mode filter 1.
