Ultra-compact acousto-optic modulator of a fibre Bragg grating in a highly birefringent suspended core fibre
On demand 
Abstract
Highly efficient and compact acousto-optic modulator of a fibre Bragg grating is reported for the first time. The device is composed of millimetre scaled components and a 1 cm grating inscribed in a four air holes birefringent suspended core fibre. The reflection of the orthogonal polarization modes is tuned by a sinusoidal electrical signal at the resonance frequency of 469 kHz. A significant modulation depth of 45% is achieved at a maximum drive voltage of 10 V. The demonstrated 4 cm long all-fibre modulator is 60% shorter compared to previous similar setups, indicating new possibilities for stable and fast switching of fibre-integrated photonic devices.

Dr. Ezequiel was awarded with the binational PhD degree in Electrical Engineering from the Federal University of Technology – Paraná in Brazil and Technical Physics Engineering from the Friedrich-Schiller-Universität in Germany in 2015. During this period, he was with the Leibniz Institute of Photonic Technology in Jena, developing all-fibre acousto-optic devices for fibre laser applications. His current research interests include the design, numerical modelling and development of high frequency fibre-based ultrasonic devices for solutions in the fields of Acousto-optic, Optoacoustics and Magnetoacoustics. He is currently a Marie Curie Fellow at the Aston Institute of Photonic Technologies in UK, leading a project in cooperation with groups in Germany and Finland.
