Abstract
The waveguide design of a GaAs based, epitaxially regrown photonic crystal surface emitting laser is discussed so as to optimise the coupling of the photonic crystal and the mode overlap with the quantum wells. Design criteria include the positioning of the quantum well and the photonic crystal layers, and the effect of varying aluminium composition in the lower cladding layer. Room-temperature, pulsed laser oscillation is demonstrated.
