摘要： Provided is an optical wavelength coupler using a multi-mode interference. The optical wavelength coupler is a planar waveguide type optical device that can distribute or couple two optical signals having different wavelengths by using the multi-mode interference. The optical wavelength coupler is suitable for integration and is small-sized. Also, the optical wavelength coupler has a low manufacturing tolerance and a low loss, and is insensitive to TE/TM polarization.

摘要： Provided is an optical distributor using a multi-mode interference and having a strong guiding PLC waveguide structure with a predetermined width and a predetermined length. A multi-mode waveguide and a temperature control heater are attached to a transmission line, and a phase of an input optical signal is varied by a multi-mode interference and a thermo-optic effect of the thin film heater. Thus, the optical signal is distributed at an optical power with a desired magnitude. A manufacturing process margin can be widened and a length of a coupler for obtaining a certain optical power distribution becomes short. Also, a phase variation range due to the temperature control heater can be decreased, thereby reducing power consumption.
