摘要： An optical interleaver of a wavelength division multiplexing (WDM) system includes an optical coupler, first and second waveguides, a high reflection mirror, and first and second phase shifters. The coupler divides an input optical signal. The first waveguide branches off from the coupler in a first direction. The second waveguide branches off from the coupler in a second direction for providing an optical path different from that provided by the first waveguide. The high reflection mirror is disposed at an end of the first waveguide for reflecting a first optical signal incident onto the first waveguide. The first phase shifter is disposed at an end of the second waveguide for multiple-reflecting a second optical signal incident onto the second waveguide. The second phase shifter is disposed at the first or second waveguide for adjusting an optical path difference between the first and second waveguides by varying its refractive index.

摘要： Provided is an optical deflector for deflecting radiation beams. The optical deflector includes: a peripheral region having a first effective refractive index; and a deflection pattern region having a predetermined shape and a second effective refractive index, wherein the second effective refractive index differs from the first effective refractive index. Here, due to the deflection pattern region having the predetermined shape, the radiation beams are deflected in a direction starting from a certain point. By using the optical deflector, the locus of a light source can be designed in one of various forms, such as a straight line, a circle, an ellipse, or a parabola.

摘要： Provided is a wavelength tunable light source that can electrically tune wavelengths by monolithically integrating an optical amplifier, a beam steering unit, and a concave diffraction grating on a single substrate. A beam is deflected by the beam steering unit when an electrical signal is applied to two electrodes installed in the beam steering unit to be incident on the diffraction grating, and then diffracted by the diffraction grating according to the incidence angle such that part of the beam with a specific wavelength is reflected, thereby achieving wavelength tuning. Since the wavelength tuning is achieved electrically, the wavelength tunable light source is structurally stable and has a rapid wavelength tuning rate.
