Abstract
In this paper, a design of an integrated wavelength-insensitive laser
Doppler velocimeter (LDV) has been proposed using planar lightwave circuit
(PLC). The proposed LDV uses arrayed waveguide gratings (AWGs) that can be
fabricated using PLC technology. Its characteristics are simulated using a
design model based on grating equations for AWGs. The simulation results
indicate that wavelength-insensitive operation can be almost obtained by
optimizing the design parameters of the proposed structure without assembly
of bulk diffractive gratings or other optical elements.
