Abstract
An optical waveguide filter including a multi-mode waveguide having a predetermined width, a predetermined length and a predetermined thickness includes a transmitting light source and a photo detector coupled to one side of the multi-mode waveguide; and a transmission line coupled to the other side of the multi-mode waveguide, wherein one hundred percent of an output optical power having a first wavelength from the transmitting light source is transferred to the transmission line, and one hundred percent of an input optical power having a second wavelength from the transmission line is transferred to the photo detector.

An optical waveguide filter using a multi-mode interference and having a predetermined width, a predetermined length and a predetermined thickness, comprising:
- a transmitting light source and a photo detector coupled to one side thereof;
- and
- a transmission line coupled to the other side thereof,
- wherein one hundred percent of an output optical power having a first wavelength from the transmitting light source is transferred to the transmission line, and one hundred percent of an input optical power having a second wavelength from the transmission line is transferred to the photo detector.
An optical waveguide filter using a multi-mode interference and having a predetermined width, a predetermined length and a predetermined thickness, comprising:
- a transmitting light source and a photo detector coupled to one side thereof;
- and
- a transmission line and a monitoring photo detector coupled to the other side thereof,
- wherein an output optical power having a first wavelength from the transmitting light source is divided at a predetermined percent and transferred to the transmission line and the monitoring photo detector, and one hundred percent of an input optical power having a second wavelength from the transmission line is transferred to the photo detector.
