Filed: 1992-08-06
Abstract: PURPOSE:To provide a buried semiconductor laser which enables fast modulation operation at high output by inserting a deep level into an n-type semiconductor layer of a current block region and a semi-insulating semiconductor layer with a deep donner level into a p-type semiconductor layer thereof, respectively. CONSTITUTION:An Fe-doped semi-insulating InP layer 3b with a deep level is inserted into an n-type InP current blocking layer 3 and a Ti-doped semi- insulating InP layer 4b with a deep donner level is inserted into a p-type InP current blocking layer 4. The p-type current blocking layer 4 in contact with an n-type InP clad layer 7 includes the high resistance semi-insulating InP layer 4b, and the n-type current blocking layer 3 in contact with a p-type clad layer 5 includes the high resistance semi-insulating InP layer 3b; therefore, a leak current hardly flows outside a light emitting part. By this constitution, a semiconductor laser which has a small threshold current of oscillation and enables fast modulation operation at high output can be obtained by restraining recombination current due to double injection of electrons and holes.

IPC: H01L21/66
Filed: 1983-11-09
Abstract: PURPOSE:To enable the rapid measurement of a semiconductor element with high accuracy, by calculating the gain compression point in the amplification characteristics of the semiconductor element from a power gain curve. CONSTITUTION:The output of a signal generator 11 is subjected to level control by a control part 16 and applied to a transistor Tr13 to be measured through a directional coupler 12. Input power at this time is measured by a wattmeter 14 and a faced lock amplifier 17 for detecting phase shift and measured value is inputted to the control part 16. Herein, the input/output power characteristics of Tr13 at the time of a same phase, that is, the change (differentiation coefficient) in output power to that in input power is calculated while input power is increased on the basis of straight line gain and a point, where power gain drops by 1dB, comes to an 1dB gain compression point and accurate output power at this time is measured by the wattmeter 15. That is, by once continuously changing input power from the straight line region of the output characteristics of Tr13 to a saturation region, a gain compression point is calculated and the shortening of a measuring time is achieved.
