    • Integrated photonic switches for nanosecond packet-switched optical wavelength conversion 

      Fidaner, O.; Demir, Hilmi Volkan; Sabnis, V. A.; Zheng, J. F.; Harris, J. S.; Miller, D. A. B. (Optical Society of America, 2006)
      We present a multifunctional photonic switch that monolithically integrates an InGaAsP/InP quantum well electroabsorption modulator and an InGaAs photodiode as a part of an on-chip, InP optoelectronic circuit. The optical ...
    • Intimate monolithic integration of chip-scale photonic circuits 

      Sabnis, V. A.; Demir, Hilmi Volkan; Fidaner, O.; Zheng, J.-F.; Harris, J. S.; Miller, D. A. B.; Li, N.; Wu, T.-C.; Chen, H.-T.; Houng, Y.-M. (IEEE, 2005)
      In this paper, we introduce a robust monolithic integration technique for fabricating photonic integrated circuits comprising optoelectronic devices (e.g., surface-illuminated photodetectors, waveguide quantum-well modulators, ...
    • Multifunctional integrated photonic switches 

      Demir, H. M.; Sabnis, V. A.; Fidaner, O.; Zheng, J.-F.; Harris, J. S.; Miller, D. A. B. (Institute of Electrical and Electronics Engineers, 2005)
      Traditional optical-electronic-optical (o-e-o) conversion in today’s optical networks requires cascading separately packaged electronic and optoelectronic chips and propagating high-speed electrical signals through and ...
    • Optoelectronic switches based on diffusive conduction 

      Demir, Hilmi Volkan; Koklu, H.; Yairi, M. B.; Harris, J. S.; Miller, D. A. B. (AIP Publishing LLC, 2006)
      We study the process of diffusive conduction that we use in our optoelectronic switches to achieve rapid optical switching (on a picosecond time scale). We present the characteristic Green's function of the diffusive ...
    • Scalable wavelength-converting crossbar switches 

      Demir, Hilmi Volkan; Sabnis, V. A.; Zheng, J. F.; Fidaner, O.; Harris, J. S.; Miller, D. A. B. (IEEE, 2004-10)
      We report scalable low-power wavelength-converting Crossbar switches that monolithically integrate two-dimensional compact arrays of surface-normal photodiodes with quantum-well waveguide modulators. We demonstrate ...
    • Self-aligning planarization and passivation for integration applications in III-V semiconductor devices 

      Demir, Hilmi Volkan; Zheng, J.-F.; Sabnis, V. A.; Fidaner, O.; Hanberg, J.; Harris, J. S.; Miller, D. A. B. (IEEE, 2005)
      This paper reports an easy planarization and passivation approach for the integration of III-V semiconductor devices. Vertically etched III-V semiconductor devices typically require sidewall passivation to suppress leakage ...
