“…There are a number of ways to realize wavelength filters in an integrated silicon photonics platform, such as arrayed waveguide gratings (AWG) [33], echelle gratings [34], Mach-Zehnder interferometer chains [35], and ring resonators. We have focused on ring resonator filters because of their compactness, low insertion loss, adaptability to many different bandwidth requirements, and ease of implementation.…”

Silicon photonics offers the possibility of a reduction in size weight and power for many optical systems, and could open up the ability to build optical systems with complexities that would otherwise be impossible to achieve. Silicon photonics is an emerging technology that has already been inserted into commercial communication products. This technology has also been applied to analog signal processing applications. MIT Lincoln Laboratory in collaboration with groups at MIT has developed a toolkit of silicon photonic devices with a focus on the needs of analog systems. This toolkit includes low-loss waveguides, a high-speed modulator, ring resonator based filter bank, and all-silicon photodiodes. The components are integrated together for a hybrid photonic and electronic analog-to-digital converter. The development and performance of these devices will be discussed. Additionally, the linear performance of these devices, which is important for analog systems, is also investigated.

“…6(b) with the noise floor of −146.46 dBm∕Hz. As the insertion loss of the SOI chip is so large, usually, two EDFAs are needed to compensate the link loss, but in this link, only one EDFA is used because the optical output power of the CWL is increased, hence the noise floor is lower relative to our previous work [15]. However, after the MZM, the dual-band filter, and the interleaver, the optical power is low for the optical LO, which reduced the optical link gain and lowered the SFDR of the link.…”

“…However, the additional distortions of the modulated optical carrier due to the re-modulation architecture limit the link spurious free dynamic range (SFDR), and thus the link dynamic range can be further enhanced by providing a coherent "clean" optical carrier or optical LO for down-conversion. In [14,15], the optical carrier suppression (OCS) scheme has been used to generate two coherent nearly "clean" optical carrier and optical LO, in which the strong LO signal is employed to get a higher optical carrier suppression ratio. Nevertheless, the higher order modulated sidebands are also generated, which would influence the properties of the LO and carrier and decrease the signal-to-noise ratio.…”

“…Moreover, relative to the transparency window in the all-pass port, we could imagine that the transmission spectrum at the complementary port would obtain a dual-band response, which would potentially have many applications including but not limited to the fields of wireless communications [19,20] and microwave photonics, such as the OCS scheme in [14,15] to achieve the clean optical carrier for modulation and optical LO for down-conversion.…”

Analog photonic link (APL) is attractive for its potential high performance of larger dynamic range, tunability, and immunity to electromagnetic interference (EMI). An APL based on the Aulter-Townes splitting (ATS)-effect-induced dual-band filter for optical carrier suppression (OCS) and the SOI signal processor has been proposed and experimentally demonstrated. The bandwidths of the two passbands are approximately 780 MHz, and the interval could be tuned from 8 GHz to more than 80 GHz in simulation. The extinction ratio is larger than 20 dB, which can provide a 20-dB suppression of the optical carrier and higher order sidebands to obtain clean optical carrier and local oscillator (LO) for modulation and down-conversion. The down-conversion APL based on the proposed dual-band OCS filter at X-band has been presented, and the spurious free dynamic range (SFDR) of the link is measured to be as high as 102.2 dB-Hz(2/3).

High‐throughput satellite (HTS) is an ideal way to realize cross‐regional massive, multifaceted digital exchange services, and it requires a signal processing module that can be massively multiplexed and has high flexibility. Due to the limitations of the frequency characteristics, microwave integrated circuits are difficult to meet this requirement. One solution to this problem is photonic integrated circuits (PICs). However, full‐size PIC satellite payloads containing main optoelectronic components are extremely challenging to implement on monolithic or hybrid integrated platforms. Here, the study demonstrates a hybrid integrated on‐chip microwave‐photonic satellite repeater with large‐scale multiplexing potential and high flexibility. This is a demonstration of a hybrid integration of a InP/Si3N4 external cavity laser, arrayed InP modulators, and semiconductor optical amplifiers (SOAs), as well as multifunctional Si3N4 signal processors, to fulfill a 1 × 4 Ka‐band repeater module with on‐chip arrayed frequency down‐conversion and outstanding narrowband photonic channelization. When combined with the full‐chip photonic RF repeater, broadband, highly integrated, and cost‐effective communications satellite payloads will become realizable more quickly in the near future.
