Title: Temperature compensating device
Inventor: TSUZUKI HIROYOSHI
IPC: G03G15/20
Filed: 1987-07-28
Abstract: PURPOSE:To stabilize the temperature in an electrical thermostatic chamber and to perform the temperature compensation of the high pressure output, by adding a parts to be used at a fixed temperature into the thermostatic chamber. CONSTITUTION:A heat-sensitive resistor 2 has a negative temperature coefficient and put into an electrical thermostatic chamber enclosed by a heat insulator together with a heat element 7. When the temperature is low in the thermostatic chamber, the resistance value of the resistor 2 is high and the voltage dividing potential set by resistors 2 and 3 is lower than that set by resistors 4 and 5. While the output of a comparator 6 is set at an H level and a transistor TR8 supplies a current to the element 7. Thus the temperature of the element 7 rise up. Then the output of the comparator 6 is inverted and the TR8 is turned off when the resistance value of the resistor 2 is reduced and the voltage dividing potential set by the resistors 2 and 3 is higher than that set by the resistors 4 and 5. As a result, the temperature is fixed in the thermostatic chamber at the voltage dividing potential of the resistors 2 and 3 that is equal to that of the resistors 4 and 5.

Abstract: PURPOSE:To improve the amplification of optical signals in SN ratio when the optical signals whose wavelength is close to a gain peak wavelength are amplified by a method wherein a ring-shaped semiconductor waveguide which has a gain is provided to a semiconductor substrate, and the length of the optical path of the semiconductor path is a multiple of an odd number by half of the gain peak wavelength of the waveguide. CONSTITUTION:Ring-shaped optical waveguides 14 and 15 possessed of an optical gain which satisfies formula (1) are formed on a semiconductor substrate 11, where L, n, and lambda in the formula (1) denote the length of an optical waveguide, refractive index inside the waveguide, and the gain peak wavelength of the waveguide respectively. The manufacturing process concerned is such that an N-InP clad layer, a non-doped InGaAs active layer, a P-InP clad layer, and a InGaAsP cap layer are successively grown on a substrate to form a DH wafer. Then, a P-side electrode is evaporated on the whole face of the wafer through sputtering. An SiO2 mask of a 8-shaped pattern 60mum or so in length of optical path is formed on the P-side electrode. The P-side electrode is removed through a wet etching method so as to leave the part unremoved where the 8-shaped pattern has formed, and then the growth layer is etched so deep as to reach to the substrate through a dry etching method. Lastly, the substrate is polished, an N-side electrode is evaporated, and the substrate is cleaved at one of the rings of the 8-shaped part, whereby an element is formed. A nonreflective coating is applied onto the cleavage concerned to improve the element in coupling efficiency with the outside.
