TL;DR: In this paper, a high-sensitivity and high-resolution silicon photonic sensor based on a microwave photonic filtering technique is proposed and demonstrated by employing a Mach-Zehnder modulator with a fixed 90 ° hybrid and a single DC bias control, this simple optical configuration is adopted to first tailor the amplitude of the optical field to achieve a power ratio in the sidebands which is then followed by an over-coupled integrated microdisk resonator (MDR) to provide a power equalization and rad phase difference in sidebands.

TL;DR: In this article, a linearised photonic mixer based on a parallel topology of two electrooptic modulators is presented, which achieves a high spurious free-dynamic range (SFDR) with additional advantages of requiring only a small amount of optical power and operating over a multioctave range.

TL;DR: In this article, a new optical frequency shifter that can shift the light frequency in the microwave or millimeter-wave frequency range is presented based on the use of stimulated Brillouin scattering gain and loss spectrums in an optical fiber to suppress one sideband of a double-sideband suppressed carrier modulation signal.

TL;DR: In this article, the pump induced change in refractive index in erbium-doped optical fiber was measured and verified by showing excellent agreement with a Kramers-Kronig transform of the measured change in absorption.

TL;DR: In this article, a new microwave photonic filter structure realising fully programmable RF filtering that can tune the filter center frequency and also reconfigure the filter shape, while exhibiting multiple taps and bipolar taps, is presented.
