Abstract: A tunable laser device (1) comprises integrally formed first and second ridge waveguides (5, 6). A longitudinally extending ridge (12) defines first and second light guiding regions (19, 20) of the first and second waveguides (5, 6) A plurality of first and second slots (27, 28) extending laterally in the ridge (12) adjacent the first and second waveguides (5, 6), produce first and second mirror loss spectra of the respective first and second waveguides (5, 6) with minimum peak values at respective first and second wavelength values. The spacing between the second slots (28) is different to that between the first slots (27) so that with one exception the minimum peak values of the first and second mirror loss spectrum occur at different wavelength values. The first and second waveguides (5, 6) are independently pumped with variable currents to selectively vary the common wavelength at which the minimum peak values of the first and second mirror loss spectra occur to produce Vernier tuning of the device.

Abstract: A laser device includes a ridge waveguide having an active layer between upper and lower cladding layers. A ridge formed in the upper cladding layer defines the width of a light guiding region in the active layer, and is formed so that a portion of the light guiding region extends into the ridge. A plurality of reflecting slots extend across and into the ridge to a depth sufficient to extend into the extending portion in order that the reflectivity of each slot is on the order of 2%. The slots intersect more than 20% of the total mode energy in the light guiding region, and this in combination with the gain of the active layer facilitates lasing within the light guiding region independently of the reflectivity of end facets of the waveguide. The laser device is particularly suitable for integrally forming with other optical components on a single semiconductor chip.
