Abstract: A reflective semiconductor optical amplifier includes a substrate, a waveguide with a buried heterostructure formed by sequentially laminating a lower cladding, an active layer, and an upper cladding on the substrate, the waveguide including, sequentially, respective straight line, curved and tapered waveguide regions. A current blocking layer surrounds the waveguide to prevent electric current from flowing outside the active layer. Selectively etching portions of the current blocking layer and the substrate around the waveguide forms a trench to reduce parasitic capacitance. Further features include a window region on one end of the tapered waveguide region, an anti-reflection surface on one end of the window region, and a high-reflection surface on one end of the straight line waveguide region.

Abstract: A multi-wavelength light source includes a substrate, a fabry-perot laser laminated on the substrate that is operated by driving current below a predetermined threshold current to generate multi-wavelength light including a plurality of peaks whose wavelengths and spacing are identical to these of WDM channels. A semiconductor optical amplifier (SOA) is laminated on the substrate in an arrangement such that a slant surface of the SOA is opposed to a side surface of the fabry-perot laser, which serves to thereby amplify the multi-wavelength light output from the fabry-perot laser. The semiconductor optical amplifier is driven in a gain saturation state to reduce the relative intensity of noise in the channels of the multi-wavelength light that are simultaneously amplified.

Abstract: A gain-clamped semiconductor optical amplifier having a horizontal lasing structure in which an oscillation direction of a laser is different from an amplification direction of a signal, and a method for manufacturing the gain-clamped semiconductor optical amplifier. The gain-clamped semiconductor optical amplifier includes a gain layer for amplifying an optical signal. A Bragg lattice layer is formed on both sides of the gain layer along a longitudinal direction of the gain layer for enabling light having a corresponding wavelength to resonate in a direction vertical to the longitudinal direction of the gain layer. A passive light waveguide restrains light resonating between lattices of the Bragg lattice layer. An electrode supplies current to the gain layer, and a current-blocking layer prevents current from flowing to an area other than the gain layer.

Abstract: Disclosed is a method for detecting synchronous information adapted to decode information recorded on a burst cutting area (BCA) on the surface of a recording medium, which method is capable of decoding the recorded information, based on only the detection of resync bytes recorded on the BCA and adapted to provide a synchronization for information recorded on the BCA following them, even when no sync byte recorded on the BCA to indicate the start point of the burst cutting area is detected. The method involves a resync byte detecting step for sequentially detecting the resync bytes following the sync byte when the sync byte is not detected, a detected information checking step for checking whether or not the resync bytes are sequentially detected in accordance with a predetermined order, and an information decoding step for reproducing and storing the information following the resync bytes when it is determined that the resync bytes are sequentially detected in accordance with the predetermined order, and decoding the stored information.
