An optical wavelength converter based on cross-gain modulation with wide input dynamic range, the converter including a semiconductor optical amplifier, a continuous wave source, and a probe beam controller. The semiconductor optical amplifier modulates probe power on the basis of pump power. The continuous wave source generates the probe beam and supplies the generated probe beam to the semiconductor optical amplifier. The probe beam controller adjusts bias current supplied to the continuous wave source and controls the probe power in proportion to the pump power.

An apparatus for transferring a wafer in a semiconductor manufacturing process, and for carrying a wafer between a cassette and a wafer chuck without an additional tool such as a tripod. The apparatus includes: a holder capable of holding the side of the wafer; a wafer transfer assembly including an actuator of the holder and a detector that detects a malfunction of the holder; and a process reactor having a vacuum exhaust port installed under a wafer chuck so as to guide gas in an axially-symmetric flow pattern. The holder grasps the rounded side of a wafer. Removal of additional tools makes the structure of an overall system more simple and an exhaust port can be installed under the reactor so as to cause processing gas to be guided in an axially-symmetric flow, resulting in an enhancement of the process uniformity.
