2015 IEEE 17th Electronics Packaging and Technology Conference (EPTC), 2015
We demonstrate chip-on-board (COB) packaged optical module operating at data rate of 25 Gb/s based on silicon photonic integrated circuits (Si-PIC). Electrical loss and packaging criteria for high-speed data transmission in COB packaging is discussed.

2019 IEEE Research and Applications of Photonics in Defense Conference (RAPID), 2019
We investigate the nonlinear optical properties of a series of two-photon absorbing chromophores in the femtosecond regime using both two-photon induced fluorescence spectroscopy and the Z-scan technique. We apply a simplified sum-over-states model to the experimental data to predict nonlinear refraction.

Journal of the Optical Society of America B, 1996
Transient-grating techniques are used to investigate the picosecond dynamics of photoexcited carriers in a range of n- and p-doped ZnSe thin-film layers grown by molecular-beam epitaxy. Two-photon absorption is employed experimentally to generate known excitation levels, comparable with those under laser action in II–VI diode structures.

Review of Scientific Instruments, 1981
An electro-optical pulse selection system for mode-locked cw lasers is described. The repetition rate of the exciting pulses can be chosen by electronically dividing the mode locker drive frequency. The shortest repetition time for pulse picking is 3 μs.

Microwave and Optical Technology Letters
AbstractIn this study, a novel freeform surface lens coupler is designed to realize the coupling functions in the hollow‐core photonic crystal fiber (HCPCF) resonator optical gyroscope. One surface of the lens is an ellipsoid. Coupling of the two HCPCF loop's ports can be directly accomplished via reflection on the ellipsoid surface.

Applying the theory of quantum nonlinear multimode optics to optimising integrated photonic devices
Quantum integrated photonics seeks to generate and manipulate non-classical states of light, a critical resource for several emerging technologies, including quantum computing and cryptography. Integrated photonic devices can leverage the stability of a solid-state platform, as well as the mature design and manufacturing capabilities of the optics ...openaire +1 more source
