We demonstrated enhancement of light emission from Er-doped silicon photonic crystal cavities, as well as cavity linewidth narrowing with increasing optical pump power at low temperature-an indication of differential gain in the system.

Photoluminescence at 1.53 um from Er: SiN x on silicon photonic crystal cavities was extracted via fiber tapers with 2.5 x greater collection efficiency compared to free space emission. Fibers were also used to demonstrate a 10 nm tuning range of 750 nm SHG emission from GaP cavities.
Tunable integrated optical modulator with dynamical photonic band transition of photonic crystals
GÖVDELİ, ALPEREN; Kocaman, Serdar (2019-01-01)
A Mach-Zehnder Interferometer based optical modulator composed of photonic crystals as phase shifters is presented. The switching process relies on the phase modulation along the arms of interferometer resulted from the photonic band shift of the photonic crystal regions. A small bulk index change leads to a large effective index difference between two arms of the interferometer and a small foot-print device can operate as a modulator. Presented MZI-based optical modulator is shown to have tunable bandwidth...

Yüce, Emre; Sokolov, Sergei; Bertolotti, Jacopo; Combrie, Sylvain; Lehoucq, Gaelle; De Rossi, Alfredo; Mosk, Allard P. (2018-10-01)
Resonant cavities with high quality factor and small mode volume provide crucial enhancement of light matter interactions in nanophotonic devices that transport and process classical and quantum information. The production of functional circuits containing many such cavities remains a major challenge, as inevitable imperfections in the fabrication detune the cavities, which strongly affects functionality such as transmission. In photonic crystal waveguides, intrinsic disorder gives rise to high-Q localized ...

Amorphous photonic materials offer an alternative to photonic crystals as a building block for photonic integrated circuits due to their shared short-range order. By using the inherent disorder of amorphous photonic materials, it is possible to design flexible-shaped waveguides that are free from restrictions of photonic crystals at various symmetry axes. Effects of disorder on photonic crystal waveguide boundaries have examined before, and it is shown that flexible waveguides with high transmission are pos...
Nonlinear optical properties of low temperature annealed silicon-rich oxide and silicon-rich nitride materials for silicon photonics
Minissale, S.; Yerci, Selçuk; Dal Negro, L. (2012-01-09)
We investigate the nonlinear optical properties of Si-rich silicon oxide (SRO) and Si-rich silicon nitride (SRN) samples as a function of silicon content, annealing temperature, and excitation wavelength. Using the Z-scan technique, we measure the non-linear refractive index n(2) and the nonlinear absorption coefficient beta for a large number of samples fabricated by reactive co-sputtering. Moreover, we characterize the nonlinear optical parameters of SRN in the broad spectral region 1100-1500 nm and show ...
