Patent JP-S6218783-A (JP)
Title: Semiconductor laser element
Inventor: YAMAMOTO SABURO
IPC: H01S5/10
Filed: 1985-07-17
Abstract: PURPOSE:To reduce the threshold current and to prevent the generation of astigmatism by forming the region where the carriers in an active layer diffuse to both sides of the stripe narrower than a channel width in the vicinity of the end plane and wider than the channel width in other parts. CONSTITUTION:(w) is a width of a stripe-form groove formed in the center of a substrate 1, namely, a V-channel, and an interval between the buried regions on both sides of said groove is W1 in the vicinity of the end plane and W2 in other parts, namely W1<w<W2. As a refractive waveguide is formed by absorbing the light in a current-preventing layer 6, a width of the optical waveguide comes in accordance with a width w of the channel 7. The carriers in an active layer are prevented from diffusing by buried layers 8 and 9. The remarkable reduction of ineffective carriers results in the remarkable reduction of the oscillation threshold current. Also, as the complete refractive index waveguide is formed in the vicinity of the end plane, the astigmatism is not generated.

When a lever is returned to neutral position, the switch SW1 is turned OFF, and the circuit T1 is turned ON when the circuit FF is reset, and the both mirrors are restored to upward direction in the same way, and the mirrors are directed outward when the circuit T3 is turned ON. During restoration operation, a manually-operated switch circuit MWS is not supplied with positive electric power, and manual operation of said switch is prohibited, and thus the circuit is protected from erroneous operation, and simple operation is permitted.
