A Mach-Zehnder Interferometer based optical modulator composed of photonic crystals as phase shifters is presented. The switching process relies on the phase modulation along the arms of interferometer resulted from the photonic band shift of the photonic crystal regions. A small bulk index change leads to a large effective index difference between two arms of the interferometer and a small foot-print device can operate as a modulator. Presented MZI-based optical modulator is shown to have tunable bandwidth up to 15.7nm. This interesting approach provides possibility of broadband, low-voltage, low-loss, high-speed and tunable optical integrated switches, modulators and multiplexers.

Integrated optical modulators with zero index metamaterials based on photonic crystal slab waveguides Yildirim, Mustafa; GÖVDELİ, ALPEREN; Kocaman, Serdar (2019-01-01) A novel integrated optical modulator design is presented using zero index metamaterial-based Mach-Zehnder Interferometer with photonic crystal phase shifters. The phase modulation relies on the shift between the photonic bandgaps having non-zero and zero effective refractive indices. A small change in the bulk index results in an effective index change between the arms of the MZI due to the disturbance of the band structure. Thus, such a structure provides a new approach for phase modulation on integrated o...
Specific features of the optical spectra in Tl2In2S3Se layered single crystals Hasanlı, Nızamı; Güler, Işıkhan (2007-06-01) The optical properties of Tl2In2S3Se layered single crystals have been studied by means of transmission and reflection measurements in the wavelength range of 450-1100 nm. The analysis of the absorption data revealed the presence of both optical indirect and direct transitions with energy band gaps of 2.16 and 2.42 eV, respectively. The observed coexistence of indirect and direct energy band gaps is related to the anisotropy of the TI-containing layered crystals. The dispersion of the refractive index is di...
Refractive index and oscillator parameters in TlGaS2, TlGaSe2 and TlInS2 layered crystals Hasanlı, Nızamı (2011-01-01) The optical properties of TlGaS2, TlGaSe2, and TlInS2 crystals have been investigated through the transmission and reflection measurements at room temperature in the wavelength range of 400-1100 nm. These measurements allowed determination of spectral dependence of the refractive index for all crystals studied. The dispersion of the refractive index is discussed in terms of the Wemple-DiDomenico single-effective-oscillator model. The refractive index dispersion parameters: the oscillator energies, the dispe...
Temperature-tuned band gap energy and oscillator parameters of TlInSeS layered single crystals Hasanlı, Nızamı; Güler, Işıkhan (2008-09-10) The parameters of monoclinic unit cell of TlInSeS layered crystals were determined from X-ray powder diffraction study. The optical properties of TlInSeS have been investigated by means of transmission and reflection measurements in the wavelength range of 500-1100 nm. The optical indirect transitions with band gap energy of 2.05 eV and direct transitions with band gap energy of 2.21 eV were found by means of the analysis of the absorption data at room temperature. Transmission measurements carried out in t...
Erbium doped silicon photonic crystals for light sources and amplifiers Vuckovic, Jelena; Makarova, Maria; Gong, Yiyang; Yerci, Selçuk; Li, Rui; Negro, Luca Dal (null; 2009-01-01) We demonstrated enhancement of light emission from Er-doped silicon photonic crystal cavities, as well as cavity linewidth narrowing with increasing optical pump power at low temperature-an indication of differential gain in the system.
