Integrated Quantum Photonic Devices

Recent achievements in the field of integrated quantum photonics have created a new opportunity for the advancement of quantum technologies. Our team has focused on quantum topics such as the design of quantum sources and photonic integrated circuits used in quantum computing and communication. We developed and manufactured quantum sources using nonlinear materials such as chalcogenide and embedding quantum dots on micro-cavities. In addition, in collaboration with the electronics team, we conduct our PNR research at room temperature.

Nonlinear Integrated Devices

We conduct research on nonlinear materials to develop and manufacture integrated optical circuits. Nonlinear materials have unique properties that make them suitable for various applications, such as frequency comb generation, tunable lasers, optical switches, etc. We also have developed quantum sources in collaboration with the integrated quantum photonic team. In addition, We are investigating materials such as lithium niobate and chalcogenide, which are compatible with industrial applications. We design and simulate the desired structures before fabricating them with the direct write method. We have the equipment to characterize the structures and measure the quality factor, the loss of fabricated waveguides and micro-rings, and other parameters.

Photonic Molecules Laser

Molecular photonics has provided an exciting and useful research field for integrated photonic systems. Photonic molecules behave similarly to molecules in physical systems. In a laboratory, photonic molecules can be created using microrings, disks, or microspheres. These structures have distinct characteristics that can be used in photonic integrated chips.  We use micro rings and microspheres to study and fabricate bimolecular and trimolecular photonic systems.

Integrated Optical Sensors

Integrated optical sensors are essential for today. These sensors are difficult to manufacture due to their hybrid structures and manufacturing challenges, such as suitable design, precise lithography, and compatibility with fiber configurations. In recent years, our team has concentrated on developing an industrialized accelerometer sensor based on the Fabry–Pérot interferometer, with both closed-loop and open-loop feedback. Furthermore, we have been developing photonic integrated circuit sensors for biological applications.
