摘要：
An efficiency-optimized scheme for Optical phased array (OPA) beam steering controlled by wavelength is proposed. In this scheme, an OPA is designed based on optical waveguides with specific interelement center-to-center spacing and length difference, by which the number of elements (phase shifters) that result in high Signal-to-Noise ratio (SNR) can be dramatically decreased. To suppress the sidelobes, we worked out a method based on gradient techniques to optimize the interelement spacing and length difference. And we mathematically prove the SNR in the case of optimized scheme is unchanged when beam steering controlled by wavelength.
