Abstract: An optical receiver of a bidirectional optical communication module is fabricated through an assembling process in which multiple modules are assembled concurrently. The module includes a first substrate formed with a groove, an optical fiber located in the groove and having a flat surface, a reflective filter inserted between the first substrate and the fiber with a predetermined inclination angle in order to reflect an incident optical signal, a second substrate supporting the fiber and mounted on the first substrate such that the flat surface.

Abstract: In a bi-directional optical transceiver module, a first waveguide transmits a optical signal received from a light source to a high reflection layer formed on a waveguide substrate. A second waveguide extends from the optical fiber to the high reflection layer. With a first mode coupling region formed by ends of the first and second waveguides near the high reflection layer, the second waveguide transmits the transmission optical signal mode-coupled from the first waveguide to the optical fiber and receives the reception optical signal from the optical fiber. A third waveguide extends from the optical detector to near an end of the optical fiber. With a second mode coupling region formed by an end of the third waveguide and the other end of the second waveguide, the third waveguide transmits the reception optical signal mode-coupled from the second waveguide to the optical detector.

Abstract: An in-situ monitoring system for a bonding process and a method therefor are provided. The monitoring system includes: a light source irradiating rays to a sample; a heating unit heating the sample; a temperature detecting unit detecting the temperature of the sample; a light detecting unit detecting the rays passing through the sample and converting the rays into an image signal; and a controlling unit receiving and outputting the image signal, and transmitting a signal for controlling the light source and the heating unit.

Abstract: Provided is an optical module. The optical module includes an optical element, an optical fiber connected to the optical element, a substrate on which the optical element and the optical fiber are mounted, and a guide groove formed adjacent to an edge of the substrate, perpendicular to the fixing groove and adapted to guide an adhesive for fixing the optical fiber to the fixing groove. The substrate has a fixing groove in which the optical fiber is seated. The optical module can improve optical fiber-fixing reliability, productivity, and the performance of optical communication.
