Inventor: INOUE TAKAHIRO
IPC: H03D1/10
Filed: 2001-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a charging/discharging circuit 41 for generating a carrier detection level Det on the basis of a received signal inverse of VC1 in a carrier detection circuit used by a receiver of an infrared ray remote controller or the like to detect the presence of a carrier that reduces an error in a charge current Ij in charging up a capacitor C2 with a minute base current of a P channel transistor (TR) QP2. SOLUTION: A TR QP1 amplifies a reference current Ij1 generated by QN1, QN2, QN3, F1 being reference current generating means, a current mirror circuit comprising QP3, QP4 lops back the reference current, which is given to the P channel TR QP2 as its emitter current. In this case, a bias voltage source 45 makes an emitter-collector voltage of the TR QP1 at an output stage of the reference current generating means nearly equal to an emitter-collector voltage of the TR QP2. Thus, the error in the charging current Ij due to the Early effect caused by a change in a collector current and then a base current depending on the emitter-collector voltage can be reduced.

Abstract: PROBLEM TO BE SOLVED: To make a void small to prevent the absorption of laser light. SOLUTION: In a p-GaAs cap layer 38, a width W3 of its upper surface is made smaller than a width W2 of its lower surface in sectional shape. Furthermore, the width W2 and a width W1 of the upper surface of a mesa part 41 have a relation of W1<W2<W1×2.5, and A height H of the mesa part 41, W1 and W2 have a relation of 0<(W2-W1)/2<0.8×H, and a width of a canopy part 42 represented by (W2-W1)/2 is sufficiently made smaller as compared with W1 and H. Therefore, when forming an n-AlGaAs current block layer 43, an air under the canopy part 42 can escape upward as the current block layer 43 grows, and a void 49 produced under the canopy part 42 can be significantly made small.  As a result, a laser light rising within the void 49 is prevented from being absorbed, and especially differential efficiency can be improved in a high output oscillation area of 50 mW or more, reducing both driving current and operation voltage.
