    摘要: The optical semiconductor device includes a spot-size converter formed on a semiconductor substrate. The spot-size converter has a multilayer structure including a light transition region. The multilayer structure includes a lower core layer, and an upper core layer having a refractive index higher than that of the lower core layer. The width of the upper core layer is gradually decreased and the width of the lower core layer is gradually increased in the light transition region. Both sides and an upper side of the multilayer structure are buried by a semi-insulating semiconductor layer in the light transition region. Light incident from one end section of the spot-size converter is propagated to the upper core layer. The light transits from the upper core layer to the lower core layer in the light transition region, is propagated to the lower core layer, and exits from the other end section thereof.

    摘要: A conventional semiconductor laser diode is small in optical power at a constant operating current and limited in ridge width when integrated with an optical device, which forces the integration to be performed by lowering the original characteristic and makes it difficult to reduce cost and power consumption. In a semiconductor laser diode, widening of the ridge width is made possible by lowering the difference in refractive indexes between the ridge and other components, diffusion current and increase in the difference of refractive indexes are prevented by forming approximately vertical grooves along both sides of the ridge, and deterioration in characteristics due to regrowth is prevented by forming a diffraction grating on the ridge. The semiconductor laser diode is integrated with an optical device such as electroabsorption type optical modulator without increase of growth cycles and without restriction of the ridge width by using a tapered waveguide.

    摘要: In a horizontal-cavity vertical-emitting semiconductor laser including an Al-containing semiconductor layer, deterioration of light output property due to oxidization of the Al-containing semiconductor layer is suppressed. A lower cladding layer, an active layer, and an upper cladding layer are stacked in this order from the lower layer on a main surface of a substrate made of GaAs. The upper cladding layer is made of AlGaAs or AlGaInP containing Al in high concentration. An emitting plane layer combining a function of preventing the oxidization of Al contained in the upper cladding layer is formed on an upper portion of the upper cladding layer, and an electric contact layer is formed on an upper portion of the emitting plane layer. The emitting plane layer is made of InGaP, and the electric contact layer is made of GaAs.
