Coupled Photonic Crystal VCSELs for Beam Steering

2007 Conference on Lasers and Electro-Optics (CLEO)
We demonstrate electrically controlled beam switching and steering in separate-contact photonic crystal heterostructures implemented with arrays of VCSELs. Switching from mutually incoherent to coherent operation is accompanied by wavelength tuning of the array elements.
