چکیده

We demonstrate the design, fabrication, and characterization of silicon photonic crystal cavities realized in a silicon on insulator (SOI) platform, operating at a wavelength of 4.4 μm with a quality factor of 13,600. Cavity modes are imaged using the technique of scanning resonant scattering microscopy. To the best of our knowledge, this is the first demonstration of photonic devices fabricated in SOI and operating in the 4-5 μm wavelength range.

Mid-infrared photonic crystal waveguides in silicon.

We demonstrate the design, fabrication and characterization of mid-infrared photonic crystal waveguides on a silicon-on-insulator platform, showing guided modes in the wavelength regime between 2.9 and 3.9 µm. The characterization is performed with a proprietary intra-cavity Optical Parametric Oscillator in a free space optical setup and with a fibre coupled setup using a commercial Quantum Cas...

Silicon photonic devices for mid-infrared applications

The mid-infrared (IR) wavelength region (2–20 μm) is of great interest for a number of applications, including trace gas sensing, thermal imaging, and freespace communications. Recently, there has been significant progress in developing a mid-IR photonics platform in Si, which is highly transparent in the mid-IR, due to the ease of fabrication and CMOS compatibility provided by the Si platform....

Mid-infrared materials and devices on a Si platform for optical sensing

In this article, we review our recent work on mid-infrared (mid-IR) photonic materials and devices fabricated on silicon for on-chip sensing applications. Pedestal waveguides based on silicon are demonstrated as broadband mid-IR sensors. Our low-loss mid-IR directional couplers demonstrated in SiN x waveguides are useful in differential sensing applications. Photonic crystal cavities and microd...

A study of thermally-induced optical bistability and the role of surface treatments in Si-based mid-infrared photonic crystal cavities

We report the observation of optical bistability in Si-based photonic crystal cavities operating around 4.5 μm. Time domain measurements indicate that the source of this optical bistability is thermal, with a time constant on the order of 5 μs. Quality (Q) factor improvement is shown by the use of surface treatments (wet processes and annealing), resulting in an increase of Q-factor from 11,500...

Optical field enhancement factor of Silicon and indium phosphide nano-cavities

Nano cavities based on silicon and indium phosphide materials have been comparedin this study, considering field intensity enhancement factor. The results of FDTD based simulations declare that the Si nano-cavity improves confined optical field about 7.7 times higher than the InP based nano-cavity. The introduced dielectric nano-cavities support resonance wavelength at about λ=1.55 μm.
