Abstract: A multisegment laser diode structure is presented in the form of two spaced-apart linear waveguide segments and two spaced-apart ring-like waveguide segments, arranged such that each of the ring-like segments is optically coupled to each of the linear waveguide segments. At least one of the waveguide segments includes an active lasing material. The waveguide segments are thus arranged such that four separate electrical contacts can be provided to four waveguide segments, respectively, thereby enabling separate driving of each of the waveguide segments.

Abstract: A wavelength selective filter device is presented suitable for use as a part of a laser cavity for processing light output of a gain section of the laser cavity. The filter structure comprises a resonator structure including at least one closed-loop resonator; and defines an optical coupler structure for coupling light from an input/output of the gain section to propagate through said resonator structure, and a light reflector structure for reflecting light filtered by said resonator structure to propagate through said resonator structure to said input/output of the gain section. The filter structure is configured so as to define two optical paths of substantially the same lengths for light propagation in the resonator structure from and to the coupler structure.

Abstract: A filtering method and optical filter structure are presented. The structure comprises an input waveguide (W1), an output waveguide (W2), and a filter stage formed by at least one closed loop resonator (R1-R2) optically coupled to the input and output waveguides. A level of the coupling from each of the waveguides to the resonator is at least 5 times greater than a loss-per-revolution of the resonator. The filter structure thus provides for reducing a bandwidth and insertion loss while filtering at least one optical channel from a multi-channel light signal.

Abstract: Disclosed are an asymmetric Y-shaped optical waveguide structure and an optical transceiver using the structure. The asymmetric Y-shaped optical waveguide structure includes a main axis optical waveguide extended in a longitudinal direction; and a branch optical waveguide extended from an extension start point in the main axis optical waveguide in a longitudinal direction as much as a predetermined region and then diverged outside. The main axis optical waveguide and the branch optical waveguide have effective refractive indexes, the magnitude relation of which is reversed for optical signals having first and second wavelength range. The optical transceiver includes an asymmetric Y-shaped optical waveguide structure, an optical fiber optically coupled to the structure for transmitting/receiving of the bi-directional optical signal, a laser diode and a photodiode. Accordingly, it is possible to miniaturize the optical transceiver, reduce a packaging cost, and improve reliability of the optical transceiver.
