Abstract :
An intracavity spatial frequency filter is proposed as a method of locking a 2D array of vertical cavity surface emitting lasers on a single, low-order transverse mode. Such a filter, which requires the interconnection of nearest-neighbour emitters, could be fabricated as a multilayer structure containing a number of multiplexed volume holograpic optical elements.
