Optical Response of an Externally Probed Active Cavity

Caption

a) A lasing cavity is probed with an external signal. (b) Measured reflection from and transmission through the cavity as a function of gain, showing an increase until lases commences followed abruptly by clamping. The device becomes a transparent perfect mirror a pre-lasing gain value: reflection in 100 percent but the transmission is finite.
