Downhole Generation Of Microwaves From Light

A system comprising:

• a first downhole electro-opto-mechanical device configured to transmit microwave radiation through a fluid, wherein the microwave radiation is generated by the first downhole electro-opto-mechanical device in response to a first light signal;
• a second downhole electro-opto-mechanical device configured to receive the microwave radiation and generate a second light signal in response to the received microwave radiation;
• and
• a light detection device coupled to the second downhole electro-opto-mechanical device and configured to generate an electrical signal in response to the second light signal, wherein the electrical signal is indicative of a chemical composition of the fluid.

A system comprising:

• a tool housing comprising:
• at least one of a transmitter electro-opto-mechanical device or a receiver electro-opto-mechanical device, wherein the transmitter electro-opto-mechanical device is configured to generate microwave radiation in response to a first light signal and transmit the microwave radiation through a fluid and the receiver electro-opto-mechanical device is configured to receive the microwave radiation and generate a second light signal in response to the microwave radiation;
• and
• a controller coupled to the tool housing and configured to determine a chemical composition of the fluid in response to the second light signal.
