摘要： A high-frequency switch includes a substrate, external conductors provided on the substrate, and a central conductor provided on the substrate, the external conductors and the central conductor constituting a coplanar high-frequency wave line on the substrate. A deflectable air-bridge is held on the external conductors via an air gap and extends out over the central conductor, the air-bridge being deflectable by an electrostatic field created by an actuation voltage applied between the wave line and the air-bridge. A control-signal conductor generates the actuation voltage between the wave line and the air-bridge. The central conductor acts as the control-signal conductor which generates the actuation voltage between the wave line and the air-bridge. The air-bridge contains a plurality of laminated thin films, the laminated thin films having variable internal stresses that are adjustable to match a particular actuation voltage selected for the switch.

摘要： A surface-emitting laser includes an active layer; multiple reflectors sandwiching the active layer; and an electrode pair connected to a power supply, through which a current is injected into the active layer. The surface-emitting laser emits at least one laser beam during a current injection period when the current injected into the active layer through the electrode pair during the current injection period is a first current and emits at least one laser beam during a current decrease period when the current injected into the active layer through the electrode pair during the current injection period is a second current exceeding the first current. The current decrease period is after the current injection period. The current injected into the active layer during the current decrease period is lower than the current injected into the active layer during the current injection period.
