Abstract

La presente solicitud proporciona un método para controlar energía óptica, el método incluye: monitorear energía óptica emitida de una fuente óptica, y juzgar si una señal de control de prueba preestablecida es recibida; cuando la señal de control de prueba preestablecida no es recibida, modular una señal de datos para emitir luz de la fuente óptica, y ajustar una corriente de polarización de la fuente óptica de acuerdo con un resultado de monitoreo de energía óptica emitida de la fuente óptica para implementar control de energía automático; y cuando la señal de control de prueba preestablecida es recibida, iniciar una prueba y sobreponer una señal de prueba a la señal de datos para formar una señal sobrepuesta y modular la señal sobrepuesta a la luz emitida de la fuente óptica, el resultado de monitoreo de energía óptica emitida de la fuente óptica es ignorado durante el periodo de prueba para mantener la corriente de polarización de la fuente óptica a un valor objetivo preestablecido; la presente solicitud además proporciona un aparato para controlar energía óptica.
