Full Name: Semicoductor Microcavity Light Emitters

Duration: 1/1/97-31/8/2000 (Finished)


  • Trinity College Dublin
  • Ecole Polytechnique de Lausanne
  • Tampere University of Technology
  • Ecole Polytechnique de Paris
  • University of Glasgow
  • MITEL Semiconductors
  • Siemens


  • To push the known technology in planar microcavity LEDs (MCLEDs) towards industrial exploitationto further develop and improve the successful InGaAs/GaAs/AlGaAs MCLED developed during (completed) ESPRIT/SMILED-project
  • To move beyond the planar microcavity concept to gain control over the laterally guided modes by texturing the planar cavity

INTEC's Role:

  • Design and fabrication of 1.3 m m bottom emitting InGaAsP/InP MC LEDs.
  • Further optimisation of bottom emitting 980 nm InGaAs/GaAs microcavity LEDs in order to improve quantum efficiency using photon recycling) and to engineer directionality,spectral bandwidth and speed/bandwidth.
  • Design and fabrication of 850 nm top emitting MCLEDs
