Abstract :
A photonic crystal pattern fabricated into ion-implanted VCSELs can engineer the spatial overlap between the optical mode and gain cross section for improved high speed operation and reduced relative intensity noise. The ion-implanted aperture should be no more than 3 mum larger than the optical aperture in order to avoid excessive electrical parasitics. 12.5 Gb/s large signal modulation of a single mode implant-confined photonic crystal VCSEL is demonstrated.
