Double Resonant Vertically Accessed Optical Waveguide Sensor
Anat Demeter-Finzi, Shlomo Ruschin
We present a new waveguided-sensing configuration combining the advantages of two effects, namely, two-wave interference and multiple-wave interference in a single sensing device.…
S-matrix absolute optimization method for a perfect vertical waveguide grating coupler
Anat Demeter, Shlomo Ruschin
Vertical coupling using a diffraction grating is a convenient way to couple light into an optical waveguide. Several optimization approaches have been suggested in order to design…
Gas Sensing through Mixed Polarization in Birefringent Porous Silicon Thin Film
Keren Hakshur, Sivan Trajtenberg-Mills, Shlomo Ruschin
The interrogation of a sensor based on a highly birefringent film irradiated by an incident beam whose polarization is oriented 45o with respect to the normal film axes is shown to…
Near infrared light amplification in Gold diffused Silicon-on-Insulator waveguides
S. Stepanov, S. Ruschin
We report near infrared optical amplification in gold diffused silicon-on-insulator waveguides by visible optical pumping. More then 30dB/cm gain was measured for a light carrier a…
Direct-Digital-Drive Microring Modulator
Yossef Ehrlichman, Ofer Amrani, Shlomo Ruschin
The method of Direct Digital Drive is applied to a microring resonator. The microring resonator is thus controlled by a segmented set of electrodes each of which is driven by binar…
Back-reflecting interferometeric sensor based on grating coupler on a planar waveguide
Anat Demeter, Shlomo Ruschin
We present a one-port sensor based on a single diffraction grating delineated over a planar optical waveguide. Distinctly to previously reported devices, the grating here is used n…
Gaussian Content as a Laser Beam Quality Parameter
Shlomo Ruschin, Elad Yaakobi, Eyal Shekel
We propose the Gaussian Content as an optional quality parameter for the characterization of laser beams. It is defined as the overlap integral of a given field with an optimally d…
