Integrated Coherent Receivers for High-Linearity Microwave Photonic Links

Abstract: Abstract-In this paper, we present a coherent receiver based on an optical phase-locked loop (PLL) for linear phase demodulation. The receiver concept is demonstrated at low frequency. For high-frequency operation, monolithic and hybrid integrated versions of the receiver have been developed and experimentally verified in an analog link. The receiver has a bandwidth of 1.45 GHz. At 300 MHz, a spurious free dynamic range (SFDR) of 125 dB Hz 2 3 is measured.

“…This opens up the possibility of a coherent microwave fiber-optic link, in which there is a marked improvement in receiver sensitivity [12]. Moreover, a technique such as phase modulation is not as prone to the nonlinearity of the modulator's transfer characteristic, leading to much greater modulation depths compared to intensity modulation [13]. The disadvantage of coherent links is the increased complexity of the receiver (Fig.3) compared to direct etection, but~ecent work has been reported on monolithically mtegrated receivers [13].…”

The disadvantage of coherent links is the increased complexity of the receiver (Fig.3) compared to direct etection, but~ecent work has been reported on monolithically mtegrated receivers [13]. Nevertheless, the majority of reported (and installed) microwave fiber-optic links to date use intensity modulation/direct detection, either with external modulators or directly modulated laser diodes.…”

“…Alternatively, an independent laser can be phase locked to the optical carrier to produce a strong LO with low excess noise. Heterodyne optical phase locked loops (OPLL) have been used to implement coherent photonic receivers 8,9 . However from a system perspective, the added complexity of the electronic control needed to implement the OPLL and high loop bandwidths necessary to compensate for semiconductor laser linewidths are both drawbacks to this approach.…”
