Abstract: PURPOSE:To attain the information transmission/reception of idle line utilizing service with less effect onto an exchange and excellent economy by placing an information transmission/reception equipment in matching with a traffic to the post position of a link of the exchange. CONSTITUTION:Subscriber line superviroty equipments SE, ME of subscriber and exchange sides always supervise a subscriber line SUBL and when an idle line is detected, they are set in a way capable of servicing. When a subscriber makes call connection from the equipment SE and starts an exchange, a link NW applies connection 1 and a call tone is sent from an outgoing register OR to the equipment SE. The subscriber dials a service special number next. Thus, the exchange switches the connection 1 to the connection 2 to connect the equipment SE to an information transmission/reception DTRE, from which service request information from the equipment SE is sent. The subscriber confirms it to dial the content of service. When the required information transmission reception is finished between the equipments SE and DTRE, the equipment DTRE sends the required minimum information only for the start of service to the equipment ME. The equipment ME offers the service to the equipment SE and the equipment DTRE and the link NE are released.

Title: Mode-locked semiconductor laser and method of changing repetition rate frequency
Inventor: ARATAIRA SHIN
IPC: H01S5/00
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To make it possible to change the repetition rate of a pulse train easily by providing a passive wave guide region with a double heterostructure which changes its equivalent refractive index according to the applied reverse bias voltage and thereby changes the repetition rate of mode-locked light. SOLUTION: In a passive wave guide region 26, an n-InP clad layer 10, a passive wave guide (i-InGaAsP layer) 12, and a p-InP clad layer 16 constitute a double heterostructure. When reverse bias voltage is applied to the double hetero-structure, a refractive index of the i-InGaAsP layer changes due to the Pockels effect and, as a result, an equivalent refractive index of the passive wave guide region 26 changes. The equivalent refractive index of the passive wave guide 26 increases with the increase of applied voltage and therefore a cycle frequency can be changed continuously. By this method, the repetition rate can be easily controlled just by changing the magnitude of the reverse bias voltage.
