    摘要: A tunable swept multi-laser system comprising a first laser source, a second laser source, a first wavelength blocking component, and a second wavelength blocking component. The first laser source has a first wavelength working range and the second laser source has a second wavelength working range. The first wavelength working range begins at a first start wavelength and ends at a first end wavelength. The second wavelength working range begins at a second start wavelength, ends at a second end wavelength, and overlaps with the first wavelength working range. The first wavelength blocking component has a first wavelength blocking range including the first end wavelength. The second wavelength blocking component has a second wavelength blocking range including the second start wavelength. The first wavelength blocking component is optically coupled with the first laser source and the second wavelength blocking component is optically coupled with the second laser source.

    摘要: An optical semiconductor device and optical semiconductor integrated circuit are provided by combining, on a semiconductor substrate, materials having different refractive indices and different temperature dependence of the refractive indices. In particular, it becomes possible to control the temperature dependence of the oscillation wavelength with a propagating region having a material and/or structure whose temperature dependence of the refractive index is different from that of a gain region of the semiconductor laser. In addition, they can be configured to have a plurality of interfaces formed along the waveguide direction of the optical waveguide so that the light reflected off the first interface is weakened by the light reflected from the remaining interfaces. Also, they can be configured with the interfaces inclined to the propagating direction so that the waveguide loss due to the reflection and refraction between the optical waveguides whose refractive indices differ from each other can be reduced.

    摘要: Objects are achieved by an optical semiconductor device comprising: a structure 61 including a substrate 50, a diffraction grating 52a, an active layer 54 and a refractive index control layer 60; and an laser element 100 including an electrode 92a for the active layer, an electrode 92b for the refractive index control layer and an electrode 92c for switching, wherein a pre-bias current is previously supplied from the electrode 92a for the active layer to the active layer 54 in a state where a switching current is not supplied from the electrode 92c for switching to the active layer 54, and then while a current Idrive for activation is supplied from the electrode 92a for the active layer to the active layer 54, the laser element 100 is turned on by supplying the switching current Isw from the electrode 92c for switching to a part of the active layer 54, as well as turning off the laser element 100 by halting the supply of the switching current Isw.

    摘要: A tunable laser diode on a semi-insulating substrate having a stripe-shaped layer structure has an intermediate layer between an active layer and a tuning layer that is grown-over by an confinement layer that is doped for the same conductivity type as the intermediate layer. An oppositely doped, lateral region is electrically connected via an identically doped lower region to the active layer. An upper region is likewise oppositely doped and is electrically connected to the tuning layer. A contact layer is essentially planarly applied on the surface of the confinement layer and has respective portions on the appertaining regions on which the contacts provided with adequate bond areas are applied with a further contact layer for the common contact.
