摘要： A passband-flattened phasar including two free space regions (48, 52) coupled by a plurality of waveguides (50) having predetermined differences between their lengths so as to act as an arrayed waveguide grating. The phasar is particularly useful in a wavelength-division multiplexed (WDM) optical communication system. The input waveguide is coupled to the first free space region through a Mach-Zehnder interferometer (MZI) (64) having two waveguide arms (66, 68) of differing lengths receiving approximately equal amounts of the input signal. The arms differ in lengths so as to produce a phase difference between them. In WDM network, the waveguide arm produces a phase difference such that the free spectral range of the MZI equals the wavelength channel spacing, such that the wavelength response of the MZI is the same for each of the WDM wavelengths. The two outputs of the MZI are coupled into the input end of a multi-mode interferometer (MMI) (44) with a lateral separation which provides a lateral spatial dispersion in the MMI equalling the lateral spatial dispersion of the conventional phasar. Thereby, a larger portion of the passband is equally passed through the phasar.

摘要： An optical device comprises a substrate (310) having at least one light-guiding core (320) and cladding material (330) surrounding the core; a cladding-modifying element (340) disposed alongside, at least in part, a portion of the light-guiding core, the cladding-modifying element being formed of a material different to the cladding material so that the refractive index difference between the material of the cladding-modifying element and the cladding material is dependent upon the temperature of the cladding-modifying element; and a heating and/or cooling arrangement for altering the temperature of the cladding-modifying element. A portion of the light-guiding core (320) is narrowed.

摘要： An optical waveguide (1) with a multi-layer core (6) comprises a substrate (2), a composite core waveguide (7) formed on the substrate (2) and at least one upper cladding layer (8) embedding said core waveguide (7). The core waveguide (7) is characterised by a composite core layer (6) comprising a first core layer (4) with a consolidation temperature T1C formed on the substrate (2) and at least one other core layer (5) formed on the first core layer (4), wherein the softening temperature T2S of at least one of said at least one other core layers (5) is equal to or less than the consolidation temperature T1C of at least one underlying core layer (4, 5).
