Abstract
We experimentally demonstrate a technique to estimate resonance wavelength of a photonic crystal cavity by spatially filtering a laser beam incident at different angles and imaging the transmitted beam profile. The transmitted beam exhibits two features: an annular beam and a central spot. Under the resonance condition, the two features overlap spatially. We develop calibration curves for the spectral characterization using transfer matrix method. The estimates from our cost-efficient technique match well with measurements obtained using a spectrophotometer.
