    • Multiplexed Mach-Zehnder interferometer assisted ring resonator sensor 

      Yadav, Mukesh; Aksnes, Astrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-04)
      A Mach-Zehnder interferometer assisted ring resonator configuration (MARC)-based multiplexed photonic sensor with a large measurement range is experimentally demonstrated. The presented MARC sensor consists of a balanced Mach-Zehnder interferometer and a ring resonator acting as a sensing component. It produces transmission responses with unique spectral signatures, which depend on the physical ...

    • Optimization of a polymer layer highly doped with Cryptophane-A for methane sensing 

      Yadav, Mukesh (Master thesis; Mastergradsoppgave, 2017-05-15)
      The main objective of this thesis is to optimize the thickness of sensitive polymer layer highly doped with Cryptophane-A for methane pre-concentration and to make the existing sensor more stable and selective towards methane. In recent years, methane detection has become a hot topic due to the strong impact of methane on the global warming and the climate change. There has also been rising ...

    • Spectral shaping of ring resonator transmission response 

      Yadav, Mukesh; Noh, Jong Wook; Hjelme, Dag Roar; Aksnes, Astrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
      We present a Mach-Zehnder interferometer assisted ring resonator configuration (MARC) to realize resonator transmission spectra with unique spectral signatures and significantly large effective free spectral ranges. Transmission spectra with unique spectral signatures are generated by changing the angular separation between the through port and the drop port waveguides of the ring resonator (RR). ...

    • Waveguide asymmetric long-period grating couplers as refractive index sensors 

      Høvik, Jens; Yadav, Mukesh; Noh, Jong Wook; Aksnes, Astrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-29)
      A highly sensitive integrated photonic transducer is designed by utilizing asymmetric long-period gratings on a silicon waveguide. These gratings are formed by periodic perturbation of the waveguide width, leading to coupling between the fundamental mode and the 1st order asymmetric leaky mode. The coupled modes are studied via finite-element and finite-difference time-domain methods. Only a single ...
