ESPRIT: SMILED

Full Name: Semicoductor Microcavity Light Emitters

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

Partners:

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

Objective:

• 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
