Chang-Hasnain Research Group

• 10 Graduate Students and 4 Undergraduates from
  EECS and AST (DE in NSE)
• Capabilities
• MBE, MOCVD, Micro-PL, 4 K cryostages, Femtosecond
  Lasers / Cross-Correlators, 110 GHz Network
  Analyzer 40 GHz scope
• Nanowires
• Grow III-V semiconductors on Si
  (CMOS-Compatible)
• Overcome lattice mismatch
• Micro-PL, SEM, TEM to analyze growth
• PL emission meV linewidth, strong blue shift

19
Chang-Hasnain Group

• Sub-wavelength Grating
• Replace VCSEL DBR with single-layer grating
• Scales easily to any wavelength
• Combined with MEMS Fast wavelength tuning
• Slow and Fast Light
• Use nonlinearities to produce extreme optical
  group velocities
• First slow light in semiconductors using CPO
• Record time shift (fast light) in semiconductors
  using intraband effects Spectral Hole Burning
  and Carrier Heating
• Optical Injection Locking
• Inject light from DFB into inexpensive VCSEL
• Record direct modulation 50 GHz
• Linearity enhancement, noise suppression
