Abstract
We demonstrate in the near infrared the coupled-resonator optical waveguide (CROW) concept that was recently proposed by Yarivet al. [Opt. Lett. 24, 711 (1999) ]. Two-dimensional photonic crystals have been used to define, in a GaAs-based waveguiding heterostructure, an array of micrometer-sized hexagonal cavities coupled through thin walls. With the photoexcitation of InAs quantum dots as an internal source, the transmission spectra of the coupled resonators show marked minibands and minigaps, in agreement with theoretical predictions.Keywords
