“…We also point out that, due to the asymmetric and Gaussian, shape of the AWG passband, the 3 dB bandwidth reduction is more accentuated than reported in other studies that were based on flat-top devices. As described before, the implementation of photonic integrated WSSs with passband-flattened AWGs [27] is a way to prevent bandwidth narrowing and the number of possible traversed nodes, as it may more than double the 1 dB bandwidth [28]. Moreover, further improvement of the ER is possible by using double-gate thermo-optic switches [21] while maintaining the wideband nature of the switching element.…”

As fiber-optic systems turn toward multi-band transmission (MBT), exploiting the complete low loss window of optical fibers, novel optical components, able to operate in bands other than the conventional C-band, become necessary. In light of this, we report on a multi-band photonic integrated 1 × 2 wavelength selective switch (WSS) operating in the O, S, C and L-bands. The photonic integrated WSS presented in this work uses a folded arrayed-waveguide grating (AWG) as the filtering element, while the wideband operation of the thermo-optic switches allows the routing of the individual channels from those bands to any of the device output ports. The operation of the WSS is experimentally validated for different bands and modulation formats. Results show error-free operation with limited penalty with intensitymodulation direct-detection (IM/DD) non-return-to-zero on-off keying (NRZ-OOK

“…It was reported that the 1 dB bandwidth more than doubled by using this approach when compared to conventional AWGs. Another approach [28] based on nonuniform AWGs showed that the optimized nonuniform AWG had a flat passband with 1 dB and 3 dB bandwidths 2.3 times larger than conventional uniform AWGs.…”

“…Moreover, this virtual point-to-point connection enables a large guaranteed bandwidth, protocol transparency, high quality of service, excellent security, bit-rate independence, and easy upgradeability. Especially, recent good progress on athermal arrayed waveguide grating (AWG) and cost-effective colorless ONUs [17] has empowered WDM-PON as an optimum solution for the modern optical access telecommunication networks.…”

We propose a novel hybrid optical sensing system for standalone, chip-scale sensing applications. The hybrid optical sensing system detects any spectral shift of the microresonator sensor output by estimating the effective refractive index using maximum likelihood estimation. The performance evaluation of the proposed hybrid sensing system in the Gaussian-noise dominant environment shows excellent estimation accuracy. This innovative approach allows fully functional integrated hybrid sensing systems, offering great potential in various chip-scale sensing applications.
