Currently an integrated photonic beamformer for electronically-steered Ku-band phased array antenna (PAA) system for satellite communications is being developed within a Dutch Point One R&D Innovation Project “Broadband Satellite Communication Services on High-Speed Transport Vehicles”, targeting instantaneous reception of the full Ku-band (10.7–12.75 GHz), squint-free and seamless beam steering,...
In this paper, we describe the design and the development of a Ku-band phased array antenna system for the reception of a digital video broadcasting by satellite (DVB-S) signal. A concept of optical beamforming is implemented to provide a squint-free beam steering over the entire Ku-band (10.7-12.75 GHz) as well as to achieve seamless tunability of the beam pointing direction. The total antenna system...
We compare the effects of low biasing and push-pull modulation on the spurious-free dynamic range (SFDR) of an analog photonic link (APL) architecture employing a pair of directly-modulated laser diodes and a balanced photodetector.
For enhanced communication on board aircraft, novel antenna systems with broadband satellite-based capabilities are required. The technology will enhance airline operations by providing in-flight connectivity for flight crew information and will bring live TV and high-speed Internet connectivity to passengers. The installation of such systems on board aircraft requires for aerodynamic reasons the...
We demonstrate an analog photonic link (APL) with a high multioctave spurious-free dynamic range (SFDR) of 120 dB.Hz2/3 at the frequency of 2.50 GHz. The APL consists of a pair of distributed-feedback laser diodes (DFB LDs), modulated in a push-pull manner, and a balanced photodetector aiming at suppressing the second-order intermodulation distortion (IMD2). At the frequency of 2.50 GHz, an IMD2 suppression...
We demonstrate a directly modulated analog photonic link (APL) capable of a high multioctave spurious-free dynamic range (SFDR). The APL consists of a pair of laser diodes, modulated in a push-pull manner, and a balanced photodetector aiming at suppressing the second-order intermodulation distortion (IMD2). In a wide frequency range of 600 MHz (2.60-3.20 GHz), an IMD2 suppression as high as 23 dB...
We study pulse transmission across a single optical ring-resonator circuit theoretically. The theory is supported by experimental measurements. From the study, we discuss intuitively the fulfillment of the causality rules in negative delay phenomenon, which occurs when the circuit possesses a negative group velocity.
A squint-free, continuously tunable optical beamformer system for phased array receive antennas is proposed and experimentally demonstrated, which involves an integrated ring resonator-based optical beam forming network, filter-based optical SSB-SC modulation and balanced coherent detection.
For enhanced communication on board of aircraft novel antenna systems with broadband satellite-based capabilities are required. The installation of such systems on board of aircraft requires the development of a very low-profile aircraft antenna, which can point to satellites anywhere in the upper hemisphere. To this end, phased array antennas which are conformal to the aircraft fuselage are attractive...
Passive optical networks (PONs) are a preferred architecture for distribution of bandwidth in the access network. The BSIK Freeband Broadband Photonics Project (BBP) looks at the design of a flexible DWDM PON which can be used to increase the bandwidth provided to the user. We present a control and management scheme for such a network which operates with the IEEE Ethernet passive optical network (EPON)...
