Title: Q-switching semiconductor laser
Inventor: FUJITA TOSHIHIRO
IPC: H01S5/00
Filed: 1985-12-24
Abstract: PURPOSE:To realize a Q-switching by controlling the polarization of the emitted light from a semiconductor laser by a method wherein one polarization component only of the binary polarizations which the polarizing direction of the emitted light intersects orthogonally is optically fed back to the semiconductor laser by the external resonator disposed outside of the semiconductor laser. CONSTITUTION:The laser beam which is emitted from one resonator surface 12 of a semiconductor laser 10 transmits a lens 14. The semiconductor laser 10 can be controlled by an injection current, for example, as binary polarizations, that is, a TM mode and a TE mode, which the polarizing direction of the emitted light intersects orthogonally. Broken lines 16 and full lines are each assumed to be the TM mode and the TE mode. These laser beams are reflected upward when the semiconductor laser is oscillating in the TM mode of 16 because of the existence of a polarization beam splitter 20 and transmit when the semiconductor laser is oscillating in the TE mode of 18. A TE mode laser beam 18 which transmitted this polarization beam splitter 20 is fed back to the semiconductor laser 10 by an external resonator 22.

Title: High frequency switching circuit
Inventor: SHIBATA KIYOHIRO
IPC: H03K17/687
Filed: 1987-11-20
Abstract: PURPOSE:To increase the isolation at the time of disconnection by cancelling the residual resistance of a switching element at the time of turning off a switching circuit by the negative resistance of a negative resistance circuit connected in series. CONSTITUTION:With a switch OFF voltage nearly OV supplied to a switching control signal input terminal 6, a switching circuit 9 is energized and a residual resistance of nearly 10OMEGA remains, but when a negative voltage is supplied to a bias supply terminal 14, since a negative resistive element 11 shows a negative resistance of nearly -10OMEGA, then they are cancelled together and the impedance when viewed from a transmission line is nearly zero. As a result, a very high isolation is obtained as the OFF characteristic of the switching circuit. Moreover, the capacitive reactance caused in the switch circuit 9 can be cancelled by the inductive reactance of an inductor 35.
