tunable 503 ns Optical Delay of 40 gbit s rz ook and rz dpsk using a wavelength scheme for phase conjugation to reduce residual dispersion and increase Delay
Optics Letters, 2009Co-Authors: Scott R Nuccio, L Christen, I Fazal, Omer F Yilmaz, Salman Khaleghi, Xiaoxia Wu, Alan E. WillnerAbstract:We demonstrate a method for a tunable Optical Delay element that allows for minimal residual dispersion and double the relative Delay. A tunable Delay of 503 ns for 40 Gbit/s return-to-zero on-off keying and return-to-zero differential phase-shift keying is shown with a reduction in residual dispersion of ~95%.

integrated remotely tunable Optical Delay line for millimeter wave beam steering fabricated in an inp generic foundry
Optics Letters, 2015Co-Authors: Zizheng Cao, E Tangdiongga, Netsanet Tessema, Sylwester Latkowski, Xinran Zhao, Zhe Chen, Valentina V Moskalenko, K A Williams, Van Den H P A Boom, A M J KoonenAbstract:A compact and fabrication-tolerant integrated remotely tunable Optical Delay line is proposed for millimeter-wave beam steering and is fabricated in an InP generic foundry. The proposed Delay line is based on a spectrally cyclic-arrayed waveguide grating feedback loop. Its major features include the tolerant architecture with reduced chip size, and bi-directional operation with simplified remote tuning. Moreover, its cyclic feature guarantees further cascaded operations either for 2D radio beam steering or for high-resolution Delay generation. The experimental results show less than 6.5-dB insertion loss of the integrated Delay line. Five different Delays from 0 to 71.6 ps are generated with less than 0.67-ps Delay errors.

phase modulation parallel Optical Delay detector for microwave angle of arrival measurement with accuracy monitored
Optics Letters, 2014Co-Authors: Zizheng Cao, Qing Wang, E Tangdiongga, H P A Van Den Boom, A M J KoonenAbstract:A novel phase modulation parallel Optical Delay detector is proposed for microwave angle-of-arrival measurement with accuracy monitored by using only one dual-electrode Mach-Zehnder modulator. A theoretical model is built up to analyze the proposed system including measurement accuracy monitoring. The spatial Delay measurement is translated into the phase shift between two replicas of a microwave signal. Thanks to the accuracy monitoring, the phase shifts from 5° to 165° are measured with less than 3.1° measurement error.
