Abstract: PURPOSE:To obtain a semiconductor laser oscillating in a wavelength of 2-3 mum having a wide range of operating temperatures without remarkably increasing an oscillation threshold value, by forming a part or all of at least one of two clad layers of a specific compound semiconductor layer. CONSTITUTION:On an InAs substrate, there are formed an N-type InAsPSb layer 2 as a second clad layer, an N-type InAsPSb light-emitting layer 3, a P-type A GaAsSb layer 13 as a first clad layer and a P-type InAsPSb layer 4 one over another and electrodes 5 and 6 are provided. A part or all of the clad layer 13 is provided by a tetra-or penta-component compound semiconductor layer consisting of a combination of Al, As, Sb and at least one of In and Ga. In the layer 13, crystals can be grown to a composition corresponding to a forbidden band width of about 1.5 eV while matching their lattices with the substrate 1. Thus, the layer 13 is allowed to have a width of the forbidden band which is greatly different from that of the light-emitting layer 3. Therefore, if a temperature is raised, a threshold value is not increased thereby since electrons are effectively entrapped in the layer 3.

Filed: 1988-06-02
Abstract: PURPOSE:To shorten a time required for recovery to a normal operation by restarting execution by correcting a byte boundary error without interrupting the execution of a program when byte boundary exception generated at the time of executing the program is detected. CONSTITUTION:When program exception is generated at the time of reading and executing an instruction in an execution program 21 on a main memory 2 by a central processing unit 3, a generated address is informed to a cancellation processing means 4 with the specification of the exception. The cancellation processing means 4 saves register information at the time of generating the exception in a system memory. And when it is decided that a processing is an exceptional processing by the limitation of the byte boundary, the instruction is read out from an address where the exception is generated, then, analyzed. Since it is impossible to set the content of a register directly on program data when it is an update instruction, the content of the register is saved to the system memory for temporal working, and the content of the system memory is transferred to a program data address with the instruction not receiving boundary limitation.
