When the input signal is changed and the output of the comparator circuit is inverted, the switch is changed over and the MOS Tr 1 impressing the input signal and the MOS Tr 2 impressing the other reference voltage constitute a differential circuit. Similarly, a current is inputted to the comparator circuit to obtain an output signal of a Schmitt circuit and a control signal of the switch circuit. Thus, the signal is inverted by a voltage VH, VL being a reference of the threshold value of the Schmitt circuit to output a signal subject to waveform-shaping.

Title: Semiconductor light-emitting diode
Inventor: UJI TOSHIO
IPC: H01L33/30
Filed: 1986-11-19
Abstract: PURPOSE:To suppress the oscillation of a laser and to easily realize a high light-output by a method wherein a transmitting region, which is composed of a material having the refractive index almost identical to that of a light- emitting region and which transmits the output light coming from the light- emitting region, is formed at the edge part of the light-emitting region and the main output-light is extracted from the transmitting region. CONSTITUTION:An n-type InP layer 12, an n-type InGaAsP active layer 13, a p-type InP layer 14 and a p-type InGaAsP contact layer 15 are formed in succession on an n-type InP substrate 11; one part of an epitaxial layer is removed by etching; a transmitting region 16 composed of an Fe-doped high- resistance InP layer is formed. The light which is emitted from a light-emitting region 22 undergoes beam divergence at the transmitting region because no light-guide is installed; the light reflected at the edge part of the transmitting region; the ratio of the light which is fed back to the stripe-shaped light-emitting region is extremely little. As a result, even when the reflection factor of an anti-reflection film is several percentages, the effective reflection factor at the front edge of the light-emitting region is less than 0.1 %, and it is easy to suppress the oscillation of a laser.
