Content
Semiconductor lasers
• Double hetero junction (DH) semiconductor lasers
• Gain-guided and index-guided semiconductor lasers
• Quantum well lasers (density of states, gain in QWs)
• Distributed feedback (DFB) lasers (oscillation condition, gain coupled DFBs)
• Surface emitting lasers (oscillation condition of VCSELs, Bragg mirror, oscillation frequencies)
• Direct modulation of semiconductor lasers (high speed modulation, damping factor)
• Frequency chirp in current-modulated lasers
• Laser noise (in tensity noise, spectral linewidth)
Electro-optic and acousto-optic modulators
• Electrooptic effect: amplitude and phase modulators
• High frequency modulation (transit time limitation, travelling wave modulators)
• Acousto-optic modulators
• Applications
Electroabsorption modulators
• Optical absorption due to an electron-hole pair
• Franz-Keldysh effect
• Quantum confined Stark Effect (QCSE)
• Interband electroabsorption modulators
• Technology and performance
• Chirping characteristics
Photodetectors
• photodiodes p-n, pin and avalanche
• Intersubband quantum well photodiodes
• Photodetector noise, Detector response time.
