Electro-optical modulator having a monomode light waveguide modulator

An electro-optical light modulator comprising:

• a pressure-sensitive signal generator including an output and operable in response to the application of pressure to produce an electrical signal at said output, said pressure-sensitive signal generator comprising an acousto-electrical piezo-electric transducer including a wafer of piezomaterial, a plurality of electrodes and counter-electrodes on said wafer forming a plurality of capacitors, and means connecting said capacitors in series so that the voltages derived from the individual capacitors add to provide the electrical signal;
• and
• monomode light waveguide modulator means including a light input for receiving a light signal, a light output for emitting a modulated light signal, and an electrical input connected to said output of said signal generator, and operable to modulate the light signal in response to said electrical signal.
