Abstract
Testing of integrated (guided-wave) optical component that uses cleaved
facets for input/output coupling has to deal with spurious Fabry-Pérot
cavity effects that can interfere heavily with observation and measurement
of the behavior of the device. This paper demonstrates a technique that takes
advantage of such interference for the reconstruction of the complete characteristics
of a generic component. By studying a theoretical model of the system, a post-process
computational tool is developed and verified through numerical testing. Starting
from a single transmittance data set, the amplitude and phase of the transmission
and reflection coefficients are reconstructed with considerable accuracy.
Initial experimental testing demonstrates consistency in reconstructing the
behavior of a real device.
