Photonic Integrated Circuit Applications. In fibre optic communication photonic devices are used to multiplex and demultiplex wavelength division multiplex wdm carrier signals. They are used to re amplify optical signals passing through long distance fibre optic cables.
The indium phosphide photonic integration platform is a mature and high performance candidate to implement these pics 1 2. They are used to re amplify optical signals passing through long distance fibre optic cables. Finely tuned light delivered through a photonic integrated circuit pic via a free space aperture or fiber optic interconnect with accompanying detection receiver capabilities enables game changing capabilities such as frequency modulated continuous wave fmcw lidar for automotive safety solutions.
From optical coherence to mography oct medical instrumen.
In addition a photonic integrated circuit can remove background noise from an rf signal with unprecedented precision which will increase the signal to noise performance and make possible new benchmarks in low power performance. Freedom photonics have recently demonstrated integrated widely tunable transmitters 3 4 and coherent receivers 4 5 6 photonic integrated circuits. Pics find their advantage in photonic as well as biomedical computing. Using the ghz precision signal processing of photonic integrated circuits radiofrequency rf signals can be manipulated with high fidelity to add or drop multiple channels of radio spread across an ultra broadband frequency range.
