	COMSOL simulates processors for fiber optics communication Enablence Technologies Inc., Ottawa, ON, Canada Required for simulating optical systems is the capacity to handle arbitrary geometries, individual and coupled processes, user-defined governing equations,...
	Modeling Metamaterials Leads to Major Breakthrough Duke University, Durham, NC In their efforts to use metamaterials to construct the world´s first working prototype of an invisibility cloak, researchers relied on modeling to lead them...

	Photonic Crystal Photonic crystal devices are periodic structures of alternating layers of materials with different refractive indices. Waveguides that are confined inside of a photonic crystal can have very sharp low-loss bends, which may enable an...
	Photonic Micro Prism To reduce radiative losses in photonic waveguide bends, a microprism can be used. If a microprism is placed between two waveguides forming a sharp bend, light will be guided between the waveguides, through the prism. This model...
	Step Index Fiber The transmission speed of optical waveguides is superior to microwave waveguides, because optical devices have a much higher operating frequency than microwaves, enabling a far higher bandwidth. This model is an example of a single...
	Stress-Optical Effects - with Generalized Plane Strain and in a Photonic Waveguide Planar photonic waveguides in silica (SiO2) have a great potential for use in wavelength routing applications. The major problem with these kinds of waveguides is birefringence. Anisotropic refractive indices result in fundamental mode...
	Second Harmonic Generation of a Gaussian Beam Laser systems are an important application area in modern electronics. With nonlinear materials it is possible to generate harmonics that are an even multiple of the frequency of the laser light. This model shows how a second harmonic...
