Abstract: ABSTRACT OF THE DISCLOSURE           An optical pickup device in which a main beam and a pair of sub-beams are used and a diffraction device is disposed between a recording medium and a light receiving device such as a photodetector is disclosed.   The diffraction device comprises first to third diffraction regions.   The second and third regions receive light beams from the recording medium which are substantially identical in amount to each other.  The light receiving device comprises a first to a fourth light receiving regions.  The first and second light receiving regions are juxtaposed, and separated by a line.  The main beam which has been diffracted by the first diffraction region is focused onto said line. The main beam which has been diffracted by the second diffraction region is focused onto the first light receiving region.   The main beam which has  been diffracted by the third diffracting region is focused onto the second light receiving region.  The sub-beams which have been diffracted by the diffraction device are focused onto the third and fourth light receiving regions, respectively.  Alternatively, the diffraction device comprises an area where one or more diffraction regions are formed.  The farthest point of the area at the side of the light receiving device is separated from the optical axis by a predetermined distance, to prevent the first-order diffracted beam from entering the optical system disposed between the diffraction device and a recording medium.

Title: Long wavelength transmitter opto-electronic integrated circuit
Inventor: MIHASHI YUTAKA
IPC: H01S5/026
Filed: 1991-09-16
Granted: 1996-03-05
Abstract: A long wavelength transmitter OEIC includes a transverse direction current injection type semiconductor laser and a high electron mobility transistor which are integrated on a semi-insulating substrate.  The semiconductor laser includes at least an AlGaInAs lower cladding layer, a quantum well active layer and a high resistivity AlGaInAs upper cladding layer successively grown on the semi-insulating substrate, disordered regions formed in the quantum well active layer by diffusions of p type and n type dopant, and an active region sandwiched by the disordered regions.  The transistor includes an operating layer and a carrier supplying layer both comprising AlGaInAs series material and formed on the high resistivity AlGaInAs upper cladding layer.  This transistor uses the upper cladding layer as a leakage current preventing layer.  This structure can be formed by only one epitaxial growth, resulting in low costs.  In addition, since the above layers are successively grown on a flat substrate, photolithography process for forming a gate of HEMT can be performed on a flat surface, so that a fine gate pattern can be formed at high precision.  As a result, a transmitter OEIC performing high speed modulation can be expected.

Abstract: A method of producing an oxide glass thin film includes a process to obtain a transparent glass film, in which volatilization of additives in a porous film deposited is effectively suppressed and which can provide an oxide glass thin film having a desired arrangement of refractive index with a low optical loss. The method is for producing an oxide glass thin film, in which glass fine particles mainly containing SiO2 with additives are deposited on a substrate to form a porous thin film and then heated to form a transparent glass film. In the method, vapor of oxides of additive components is mixed in an atmosphere in which the porous thin film is heated to form the transparent glass film, whereby stopping the volatilization of the additives in the porous film deposited, preventing diffusion of the additives added to a core layer, and preventing the volatilization of glass transition temperature lowering components of additives (P2O5, B2O3. GeO2, etc.). By these, a desired arrangement of refractive index may be obtained, and an oxide glass thin film may be obtained while lowering the optical loss such as the optical scattering, which could be caused by bubbles in an unsintered portion.
