Abstract: A multiwavelength transmitter comprises several laser sources (1) each configured to generate light of a different wavelength and a first array waveguide grating (2) arranged to direct light from each of the laser sources (1) into a first waveguide. The transmitter further comprises several electroabsorption modulators (7) each arranged to modulate light at one of the wavelengths with a respective data signal and a second array waveguide grating (6) arranged to direct each of said different wavelengths of light from the first waveguide to a respective one of the modulators (7). The optical modulators (7) are reflective optical modulators and the second array waveguide grating (6) is arranged to direct the modulated light reflected from each of the optical modulators (7) back into the first waveguide. An optical circulator (5) is provided in the first waveguide to couple modulated light from the second array waveguide grating (6) into an output waveguide. The laser sources each comprise a respective reflective semiconductor optical amplifier (1) and share a common cavity reflector (3). The first array waveguide grating (2) is located in the optical path between the semiconductor optical amplifiers (1) and the common cavity reflector (3). The transmitter has the advantage that it can be manufactured by hybrid integration of a monolithic wavelength generation sub-module and a monolithic data modulation sub-module.

Abstract: It has been demonstrated that B containing glasses are sensitive to radiation in the band 225-275 nm and, therefore, B2O3 glasses are particularly adapted to receive refractive index modulation, e.g., to make reflection gratings. Glasses containing SiO2 and B2O3 are particularly suitable when the grating is to be localized in the cladding of a fiber. Glasses containing SiO2, GeO2, and B2O3 are suitable when the grating is in the path region of a waveguide, e.g., in the core of a fiber.

Abstract: A planar waveguiding device includes at least on section of core which is located between and adjacent to two grooves. The refractive index within the grooves is substantially equal to one and the grooves are located so that the evanescent fields of optical signals travelling in the core extend into the grooves. Preferably the grooves have a direct interface with the core and they extend through a layer located above the core into a layer located below the core. Where the cores have bends, e.g. bends with radii of curvature below 2 mm the grooves are located both inside and outside the bends.

Abstract: An arrayed waveguide grating [WDG] comprises I/O slabs (53a, 53b) interconnected by a grating region (51). The grating region (51) comprises many, e.g. at least 25 and preferably 50 to 500, individual cores (61,62,63), which have different lengths so as to provide wavelength selectivity by causing phase changes in light conveyed between the I/O slabs (53a, 53b). There are bends (64) for providing the different lengths and, to improve optical guidance round the bends, empty (R.I.=1) grooves (71) are located adjacent to the inside (71.1) and outside radii (71.2) so that the evanescent fields extend into the grooves (71). In order to keep the dimensions small, which improves the optical accuracy, tight bends (preferred radii of curvature of less than 2 mm and especially less than 500 &mgr;m) are desirable. The grooves conveniently have tapered ends and they extend into straight portions adjacent to the bends. The WDG is preferably implemented in silica glass with dopants to adjust the refractive index and/or the melting point.
