Microscale multi-functional optical structure

An optical module comprising:

• a multi-functional optical structure including a substrate, a first layer formed on the substrate, a multi-functional optical function unit formed using a second layer formed on the first layer to provide various optical functions with the substrate and the first layer, and at least one optical coupling wire formed to include a wire end portion formed to come into close contact with a preset region on the second layer to transmit and receive an optical signal to and from an optical waveguide;
• a photoelectric conversion element unit optically coupled to the multi-functional optical structure to convert the optical signal output from the multi-functional optical structure to an electrical signal;
• an electrical signal amplification unit electrically connected to the photoelectric conversion element unit to change a waveform of the electrical signal received from the photoelectric conversion element unit;
• and
• a controller electrically connected to at least one of the multi-functional optical structure, the photoelectric conversion element unit, and the electrical signal amplification unit to control a function of the at least one of the multi-functional optical structure, the photoelectric conversion element unit, and the electrical signal amplification unit.
