IPC: G02B6/122
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent the spread of regions adhered with adhesives of the connecting surface of waveguides and reins having an adhesive function by allowing the adhesive and resins having the adhesive function to escape from above the connecting surfaces of the waveguides in the connection of the waveguides and the optical fibers. SOLUTION: The waveguide device 1 is constituted on the assumption that the optical fibers are connected to, for example, surfaces 8d. Plural grooves 3 are formed on the surfaces 8a, 8b, 8c not formed with the optical waveguides 2 among the surfaces of the waveguide device 1. These grooves 3 function to allow the adhesives or the resins embodying the adhesive function applied on the connecting surfaces 8d to escape from the connecting surfaces 8d when the optical fibers are connected to these connecting surfaces. The sectional shape thereof may be arc, polygonal and other shapes in addition to a V shape and are not particularly limited.

Title: Lanthanum hexaboride-coated thermoelectron emitting material
Inventor: SUZUKI YOSHIHISA
IPC: H01J1/15
Filed: 1988-05-25
Abstract: PURPOSE:To reduce the power consumption at the time of resistance heating by coat-processing lanthanum hexaboride on the surface of a high-melting point metal. CONSTITUTION:Lanthanum hexaboride 2 is coated around a base material 1 made of a high-melting point metal, e.g., tungsten, in a straight line shape to form a thin straight line-shaped cathode, the lanthanum hexaboride 2 is plasma flame-coated, for example. When a thermoelectron emitting material coated with lanthanum hexaboride 2 with a high thermoelectron emission capability on the base material 1 made of a high-melting point metal is used as a cathode or a filament, the power consumption at the time of resistance heating can be reduced. Thermoelectrons with the quantity higher by two digits than that for tungsten can be emitted at the same temperature, various forms such as a linear, coil or ribbon shape can be formed by overcoming the poor machining shape due to fragility.

Title: Formation of semiconductor fine configuration, manufacture of inp diffraction grating, and manufacture of distributed feedback type laser
Inventor: MUROTANI YOSHIHARU
IPC: H01S5/12
Filed: 1993-05-31
Abstract: PURPOSE:To manufacture a low distortion distributed feedback type laser for analog modulation which has an ununiform diffraction grating. CONSTITUTION:Electron beam resist 1 is uniformly spread on an InP substrate 2. Electron beam exposure is so performed that the electron beam dosage in the central part is larger than at both of the end portions. In this case, the resist diffraction grating pattern formed in the electron beam resist by proximity effect is low and narrow in the region where the electron beam dosage is large in the central part, and high and wide in the region where the electron beam dosage is small in both of the end portions. In the central part of the diffraction grating, a lambda/4 phase shift 3 is formed. This resist pattern is subjected to dry etching using Cl2 based gas, and transferred on the InP substrate 2. Thus a diffraction grating having an ununiform shape is obtained. A distributed feedback type laser is manufactured by growing in order an optical guide layer, an active layer and a clad layer on the substrate.
