“…17 Wide bandgap III-nitride semiconductor, such as gallium nitride (GaN), is well-known optoelectronic material for light-emitting diodes and laser application. 18,19 However, it has been recently determined as a potential material system for technologies, such as PhC-based circuits and applications. [20][21][22] AlN as a buffer layer is significant for fabrication of GaN, which is in the previous study has reported that the growth of GaN was deposited on the AlN buffer layer.…”

In this article, we report modeling, simulation, and analysis of shifting 2D photonic crystal cavity side holes in GaN-AlN-sapphire layered structure. The design was simulated with Lumerical finite-difference time-domain. A lattice constant a, 157 nm, and a hole diameter d, 106 nm, were used in the design. The cavities are based on L3, which we demonstrated by simply shifting two holes away from a line cavity with distances of 132, 142, and 152 nm, respectively. The highest quality factor, Q, value achieved is 2.25 × 104 at 152-nm cavity distance.

Based on the self-collimation effect of light propagating inside a photonic crystal, we demonstrate a novel concept for a compact Mach-Zehnder interferometer. The properties of these self-collimated beams are such that we can manipulate them to form the beam splitters and mirrors of the Mach-Zehnder interferometer in a very compact area of 20x20 μm 2 . We obtain the unidirectional output behaviour characterized by the high contrast in the telecommunication-wavelength signal at the two outputs of the photonic crystal Mach-Zehnder interferometer. The experiments are done using optical transmission spectroscopy and far-field optical microscopy. This photonic crystal Mach-Zehnder interferometer holds a promise for a compact Mach-Zehnder modulator, inspired by recent reports of NEMS-based photonic crystal membrane.

“…The data plotted in Fig. 4 were smoothed to take out the high-order Fabry-Perot fringes arising from the cavities delimited between the facet of waveguides IN1, OUT1, OUT2 and the waveguide/PhC interfaces [20] and the low-order Fabry-Perot fringes, mainly arising from the shorter cavities delimited between the waveguide/PhC interfaces. These fringes can be suppressed by improving the mode-matching between waveguide and PhC, for example by using rib waveguides instead of ridge waveguides [21], or by entering the light into the PhC with a free-space beam and using an antireflection coating structure [22].…”

Abstract:We demonstrate a compact silicon photonic crystal MachZehnder interferometer operating in the self-collimation regime. By tailoring the photonic band structure such as to produce self-collimated beams, it is possible to design beam splitters and mirrors and combine these to a 20 × 20 µm 2 format. With transmission spectroscopy we find a pronounced unidirectional optical output, the output ratio being as high as 25 at the self-collimation wavelength. Furthermore, the self-collimated beams and the unidirectionality are clearly observed in real space using near-field and far-field optical microscopy. Interpretation of the optical data is strongly supported by different types of simulations. for propagation of electromagnetic fields within an arbitrary photonic structure, which allows one to compute a steady state response for a single frequency.
