Vector Modal Solution of Evanescent Coupler - Lightwave Technology, Journal of
We present a vector modal solution for the evanescent coupler comprising an optical fiber and a slab waveguide. We identify the normal vector ridge modes of the device for different configurations. The dispersion characteristics and the power transmission properties of these modes are presented. Also, the effect of the proximity between the waveguides on the ridge modes is investigated.
متن کاملFiber-optic modal coupler using periodic microbending.
Periodic coupling between the various modes in an optical fiber is of current interest in interferometric and sensor applications. Coupling between the two cross-polarized modes of a single-mode birefringent fiber has been studied,1 as has coupling between the LP0 1 and LP 11 modes in a circularly symmetric fiber. 2 The latter case was achieved by periodically squeezing the fiber. It has been d...
متن کاملHighly selective evanescent modal filter for two-mode optical fibers.
Efficient and selective coupling between a single-mode fiber and the LP(11) mode of a double-mode fiber is demonstrated in an evanescent directional coupler. With greater than 90% coupling to the LP(11) mode, suppression of the coupled power to the lower-order LP(01) mode was measured to be at least 24 dB. This device has application as a modal filter for the construction of in-line all-fiber o...
متن کاملSimulation of Vector Mode Grating Coupler Interfaces for Integrated Optics
The use of grating couplers to couple light near vertically in and out of optical slab or film waveguides represents an attractive method to interface optical fiber to photonic ICs. Newly developed fiber technologies exploiting vector mode polarization and orbital angular momentum (OAM) are inherently threedimensional and interfaces for such beams require the solution of fully general 3D models...
متن کاملNormalization of Experimental Modal Vectors to Remove Modal Vector Contamination
When modal vectors are estimated from measured frequency response function (FRF) data, some amount of contamination in terms of random and bias errors is always present. The sources of these errors may be the experimental data acquisition process (calibration inconsistencies, averaging limitations, leakage errors, etc.) or due to limitations of the modal parameter estimation methods (mismatch b...
