Optical coupling between monocrystalline colloidal crystals and a planar waveguide
نویسندگان
چکیده
We have experimentally demonstrated an optical material structure consisting of monocrystalline colloidal crystals and a planar waveguide. We have performed experimental studies of light coupling into the waveguide structure via colloidal gratings, as well as the multiplexing capability of the structure. Effective index obtained from measured parameters agrees well with theoretical calculations. Effect of crystal nonuniformity on diffraction line shape and width, as well as possible applications are discussed. © 1999 American Institute of Physics. @S0003-6951~99!01849-5#

Efficient excitation of self-collimated beams and single Bloch modes in planar photonic crystals.
Using finite-difference time-domain calculations, we investigate out-of-plane coupling between a square-lattice planar photonic crystal and a conventional waveguide located above the photonic crystal. We couple a waveguide oriented in the gamma(chi) direction to a photonic crystal mode in the second band and show that anticrossing takes place. In this way, a self-collimated beam is launched in ...
متن کاملTwo-dimensional colloidal crystal corrugated waveguides.
We demonstrate, for what is to our knowledge the first time, two-dimensional (2D) corrugated waveguides at optical wavelengths obtained by use of 2D colloidal crystals. We report experimental studies of light coupling into and out of the waveguide structure. The diffracted light shows interesting optical properties that exist only in such 2D grating structures. Field distribution of the fundame...

Currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twomechanisms s...
متن کاملUsing of Broadened Asymmetric Waveguide Structure for 980nm Diode Laser
Laser diode beam divergence is the main parameter for beam shaping and fiber optic coupling. Increasing the waveguide layer thickness is the conventional method to decrease the beam divergence. In this paper, the broadened asymmetric waveguide is introduced to decrease the divergence without increasing the optical power. The asymmetric waveguide was used to shift the vertical optical field to n...
متن کاملPumping Planar Waveguide Amplifiers Using a Coupled Waveguide System
A novel scheme is presented that can be used to efficiently pump optical waveguide amplifiers. It is based on the coupling between two adjacent waveguides, where pump light is gradually coupled from a nonabsorbing pump waveguide into the amplifier waveguide. The coupling between the waveguides in such a configuration is calculated using an improved coupled mode theory (CMT). The proposed distri...
