A lasing cavity can provide a substantial portion of a path over which data, messages, communication signals, or other information travels from a sender to a recipient. The lasing cavity can support light amplification by stimulated emission of radiation. The sender can be coupled to an input port of the lasing cavity, while the recipient can be coupled to an output port of the lasing cavity. The sender can input information at the input port via applying energy to the lasing cavity, removing energy from the lasing cavity, perturbing the lasing cavity, lengthening the lasing cavity, shortening the lasing cavity, or otherwise inducing a cavity change or a dynamic response. The recipient can receive the information via monitoring the lasing cavity at the output port for changes or responses caused by the sender at the input port. |
