    • All-fiber-integrated soliton-similariton laser with in-line fiber filter 

      Zhang, Z.; Öktem, B.; Ilday, F. Ö. (Optical Society of America, 2012-08-16)
      We demonstrate an all-fiber-integrated Er-doped fiber laser operating in the soliton-similariton mode-locking regime. In the similariton part of the cavity, a self-similarly evolving parabolic pulse with highly linear chirp ...

    • Effect of Mg doping in the barriers on the electrical performance of InGaN/GaN-based light-emitting diodes 

      Zhu, B.; Zhang, Z.; Tan, S. T.; Lu, S.; Zhang, Y.; Kang, X.; Wang, N.; Hasanov, N.; Demir, Hilmi Volkan (Elsevier B. V., 2018-04)
      In this work, we report how the Mg doping in the barriers affects the electrical performance of InGaN/GaN-based light-emitting diodes. When compared with the reference device that does not have Mg doped quantum barriers, ...

    • From aluminum foil to two-dimensional nanocrystals using ultrasonic exfoliation 

      Lu, W.; Birmingham, B.; Voronine, D. V.; Stolpman, D.; Ambardar, S.; Erdoğan, Deniz Altunöz; Özensoy, Emrah; Zhang, Z.; Solouki, T. (American Chemical Society, 2021-04-15)
      Al nanostructures have unique optical properties such as widely tunable surface plasmon resonances from deep UV to NIR that can be used for label-free fluorescence enhancement and surface-enhanced Raman scattering. Various ...

    • Narrow electroluminescence in bromide ligand-capped cadmium chalcogenide nanoplatelets 

      Thung, Y.T.; Zhang, Z.; Yan, F.; Demir, Hilmi Volkan; Sun, H. (AIP Publishing LLC, 2022-06-15)
      Colloidal zinc blende II–VI semiconductor nanoplatelets (NPLs) demonstrate as a promising class of materials for optoelectronic devices due to their unique excitonic characteristics, narrow emission linewidth, and quantum ...

    • Seizure detection using least eeg channels by deep convolutional neural network 

      Avcu, Mustafa Talha; Zhang, Z.; Chan, D. W. S. (Institute of Electrical and Electronics Engineers Inc., 2019)
      This work aims to develop an end-to-end solution for seizure onset detection. We design the SeizNet, a Convolutional Neural Network for seizure detection. To compare SeizNet with traditional machine learning approach, a ...

    • Sub-50 fs Yb-doped laser with anomalous-dispersion photonic crystal fiber 

      Zhang, Z.; Şenel, Ç.; Hamid, R.; Ilday, F. Ö. (Optical Society of America, 2013)
      We report on the generation of 42 fs pulses at 1 μm in a completely fiber-integrated format, which are, to the best of our knowledge, the shortest from all-fiber-integrated Yb-doped fiber lasers to date. The ring fiber ...
