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 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.

The device comprises a filter structure that has an input for receiving the multi-frequency input light signal, a first output for outputting a first light component of the input light signal including light of said predetermined frequency range, a second output for outputting a second light component including a remaining portion of the input light signal, and an intermediate input. The first output and the intermediate input of the filter structure may be connected to, respectively, input and output of a tunable frequency-selective optical unit, which may be a second filter structure, amplifier, attenuator. By using the second filter structure with a different tuning range as compared to that of the first filter structure such that these tuning ranges define overlapping spectra of the filter structures, a two-stage filter device is provided.
