Photonic sensors in our ever-connected world

For those who are unfamiliar, I have a pleasure to recall that, Photonic sensors are defined as sensors that sense, emit, receive and convert the light energy into electrical signals. Photonic sensors were primarily used in high performance application such as night vision. However, photonic sensors has become ubiquitous, and have found invaluable in the fields such as in motion detection, blood oxygen monitors, cameras of cell phones, etc.
