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.

Near one end surface of the slider is provided the optical waveguide that pierces through the slider in a direction of the thickness thereof.

摘要： An optical integrated circuit having optical devices is fabricated. These optical devices must be biased in the mutually opposite directions. If such an optical integrated circuit is fabricated using a conductive semiconductor substrate as conventionally, it is not possible to drive the devices by a single power supply since the substrate side is shared as a common polarity by the devices. The present invention realizes a structure where both anode and cathode of each device can be isolated electrically by conventional process technology and provides an optical integrated circuit which can be driven by a single power supply.An optical integrated circuit is formed on a semi-insulative or insulative substrate. A high resistivity region which extends at least from the active layer to the substrate and includes part of an optical waveguide between the devices is formed so as to electrically isolate the anode and cathode of each integrated device from the other device.
