Title: Semiconductor light emitting element
Inventor: IMANAKA KOUICHI
IPC: H01S5/227
Filed: 1983-09-16
Abstract: PURPOSE:To produce the title element with excellent light emitting efficiency eliminating any current leakage channel by a method wherein, in a buried type semiconductor light emitting device with buried layers at both sides of a double hetero structure, the buried layers are composed of a lower layer comprising mixed crystal of InP or GaInAsP and an upper semi-insulating AlxGa1-xAs layer formed by organic metallic vapor growing process. CONSTITUTION:An N type InP layer 7 as a lower clad layer is coated with an active layer 8 whereon an N type upper clad layer 9 is deposited to form a double hetero structured light emitting element. Next both sides of the layer 9 including a part of the layer 7 are removed from the surface leaving the central part as a stripe. Later, the removed parts at both sides are buried in buried layers 10 to be current strangulating layers. At this time, the layers 10 are composed of a laminated body of a lower layer comprising non-doped InP or GaAsP coming into contact with the substrate 7 and an upper layer comprising semi- insulating AlxGa1-xAs. Through these procedures, the energy gap of the layers 10 may be augmented to restrict the current flowing therein.

Abstract: PURPOSE:To detect the EOL at high speed, and also, to execute the parallel decoding processing of an MH encoder/decoder by providing a zero detector for detecting the existence of the EOL and a decoder for deciding the detector from which zero is outputted, in a register. CONSTITUTION:Data from a data bus sets a first word from a register 2 to '1', and also, sets a second word to the register 2. When one word is constituted of (m) bits, 11 continuous bits are retrieved by inputting the data extending from 2<10> bits to 2<0> bits of the register 2 to an nmax-th zero detector and whether an EOL exists in the word or not is checked. When it does not exist, an output A is controlled by an OR circuit, and (m) bits of the contents of the register are transferred successively. When '0' is outputted, a tri-state buffer is opened and a binary number (n) and an EOL detecting signal are outputted to A and B, respectively. An EOL detecting circuit sets two words in parallel and can output them at the high speed.
