Microwave generator circuit having oscillator and controller responsive to separate wavelengths

An optically controlled microwave, generator, comprising an oscillator circuit and a modulator.

• wherein the oscillator circuit is excitable optically;
• Wherein a microwave carrier generated by the oscillator circuit can be modulated by an optically controllable electric switch contained in the modulator;
• and
• wherein the oscillator circuit is excitable with light of a first wavelength, wherein the modulator is controllable with light of a second wavelength, and wherein the oscillator circuit is insensitive to the light of the second wavelength, while the modulator is insensitive to the light of the first wavelength.

An optical transmission system comprising an optical transmitter and an optical receiver,

• wherein the optical transmitter generates and emits light of a first wavelength and light of a second wavelength, the light of the second wavelength being modulated for transmitting a signal, and
• wherein the optical receiver includes an optically controlled microwave generator, comprising:
• an oscillator circuit and a modulator,
• wherein the oscillator circuit is excitable optically, and
• wherein a microwave carrier generated by the oscillator circuit can be modulated by an optically controllable electric switch contained in the modulator.
