Integrated photonic devices
The use of nanophotonic technologies for making photonic structures leads to the implementation of integrated photonic devices with novel features and functionalities. The integration capacity of photonic structures enables multiple and complex functionalities on a single chip. Moreover, it is envisaged that these integrated circuits will be smaller and use less power than existing devices. For these reasons, demand for photonic devices is expected to grow in the same way that the demand for microelectronics grew in previous decades. Integrated photonics offers benefits in speed and bandwidth. Additionally, the implementation of structures with exact nanometric control of light leads to an increased and direct interaction with underlying materials, tissues, or cells. This offers great potential for the implementation of sensors for detecting small-scale elements or processes.
These features of photonic structures lead to a wide range of applications in various industrial sectors:
- Passive photonic devices for the implementation of basic functionalities such as
power splitters, multiplexors, filters, etc.
- Photonic processing devices, delay lines, slow wave and highly dispersive structures.
- Optical beamforming including Butler matrices.
- Highly sensitive and selective sensors for different fields of applications such as medicine or defence, for detecting explosive and military gases, chemical elements, and pathogens.
