Direct measurement of photonic band structures by second harmonic generation
Quantum Electronics and Laser Science Conference, 2005. QELS '05(2005)
Abstract
By exploiting the phase sensitivity of second harmonic generation, we measure photonic band structures in PLLN waveguide arrays. Furthermore, we show that the concept can be applied to other photonic structures, as, e.g., photonic crystals.
