Testing and experimental characterization of a fabricated photonic integrated circuit (PIC)-based Sin-Sin2 frequency discriminator: Preliminary results
Abstract
We present, for the first time to the best of our knowledge, the preliminary experimental results of a fabricated Linearized Optical Frequency Discriminator (LOFD) device called the Sin-Sin2. This photonic integrated circuit (PIC) device was locally designed in Ateneo de Manila University, Philippines and was fabricated using electron beam lithography through the assistance of Universitat Politècnica de València, Spain. We tested and characterized the device using the PIC Characterization laboratory of Chiang Mai University, Thailand. We observed power readings resemble our analytical simulations with some deviations. The results obtained from this initial testing and characterization will be used to improve the next design iteration of our devices.
