Wide bandwidth and high resolution planar filter array based on DBR-metasurface-DBR structures.
We propose and experimentally demonstrate a planar array of optical bandpass filters composed of low loss dielectric metasurface layers sandwiched between two distributed Bragg reflectors (DBRs). The two DBRs form a Fabry-Pérot resonator whose center wavelength is controlled by the design of the transmissive metasurface layer which functions as a phase shifting element. We demonstrate an array ...
متن کاملHigh-Speed Frequency Modulated DBR Lasers for Long-Reach Transmission
We present a novel high-speed transmitter consisting of a frequency modulated DBR laser and optical filters. The refractive index modulation in the phase control region of the DBR laser allows highspeed frequency modulation. The generated frequency modulated signal is converted to an intensity modulated signal using the edge of the optical filter pass band. We present theoretical simulations of...
متن کاملDBR: Depth-Based Routing for Underwater Sensor Networks
Providing scalable and efficient routing services in underwater sensor networks (UWSNs) is very challenging due to the unique characteristics of UWSNs. Firstly, UWSNs often employ acoustic channels for communications because radio signals do not work well in water. Compared with radio-frequency channels, acoustic channels feature much lower bandwidths and several orders of magnitudes longer pro...
متن کاملSampled-Grating DBR Laser-Based Analog Optical Transmitters
Sampled-grating distributed Bragg grating (SGDBR) laser-based widely tunable optical transmitters are investigated for application in high-performance analog links. More than 45 nm tuning range, 40 dB sidemode suppression ratio, and peak relative intensity noise below 153 dB/Hz is measured. SGDBR lasers integrated with semiconductor optical amplifiers and electroabsorption modulators (EAMs) are...
متن کاملDirect modulation bandwidth enhancement of strongly injection-locked SG-DBR laser
Significant enhancement in the direct amplitude modulation bandwidth of an SG-DBR laser has been demonstrated under strong injectionlocking conditions, where the wavelength detuning between the master and the free-running SG-DBR slave laser is varied from 28.58 to 13.6 nm. It is demonstrated that the relaxation resonance frequency of a strongly injection-locked SG-DBR laser increases from 1.05 ...
