A device for use in optical signal control is presented. The device comprises an amplification waveguide, including a pumpable medium, and a reference and a control inputs and an output selectively allowing transmission of light respectively into and out of said amplification waveguide. The reference input, the amplification waveguide and the output define together a transmission scheme for reference light through the pumpable medium. The control input and the amplification waveguide define a depletion scheme for the pumpable medium and control light. The device thus allows for controlling an output signal, formed by the transmission of the reference light, by controllable depletion of the pumpable medium. |

1. A device for optical signal control, the device comprising
an amplification waveguide comprising a pumpable medium, a reference input, a control input, an output,
wherein the reference input, the control input, and the output selectively allow transmission of reference light into and out of the amplification waveguide, a transmission circuit, formed by the reference input, the amplification waveguide, and the output, for transmitting the reference light through the pumpable medium from the reference input to the output, and a depletion circuit for the pumpable medium and control light, the depletion circuit formed by the control input and the amplification waveguide, wherein the control light via the control input depletes the pumpable medium when the pumpable medium is pumped, and wherein the device is capable of controlling an output signal, formed by the transmission of the reference light through the pumpable medium from the reference input to the output, by the controllable depletion of the pumpable medium. |
