A new method based on introducing a photonic crystal fiber (PCF) in-line interferometer for hydrogen sensing is demonstrated. One end-face of the PCF and part of the outer-face of the fiber are plated ...

A 10-20 GHz tunable LC-VCO core using this inductor was also fabricated. Because of the multi-stage variable inductor, 20 GHz operation having over 10 GHz continuous tuning range with phase noise of ...
