Integrated Photonic True-Time Delay Beamformer for a Ka-band Phased Array Antenna Receiver

Wideband Rapidly Tunable Delay-Controlled Optoelectronic Oscillator

“…However, with the advancement of CMOS compatible photonic integrated circuits (PICs), many designers are aiming to benefit from photonic assisted electronics while simultaneously enjoying the associated advantages of integration such as miniaturization, lower cost and scalability. A few successful examples include an integrated imager [9] implemented using nanophotonic delay elements, and partially integrated beamformers with tunable optical delay lines based on cascaded ring resonators [10] and Mach-Zehnder Interferometers [11]. Similarly, OEOs integrated on platforms such as Silicon on Insulator (SOI) and Indium Phosphide [12][13][14] have previously been reported.…”

“…In this case, the group delay experienced by the input optical signal, modulated with a monocycle pulse with a bandwidth of 0.5-5GHz, can be tuned from 0 to 100ps equivalently delaying the detected UWB pulse. Such a tunable optical delay line has applications ranging from high speed equalization in photonic links [16] to optical coherence tomography [17] and photonic assisted beamformers [1,9,11].…”
