“…The present research of AWG demodulation systems tends to improve the resolution and dynamic range at the same time. Trita proposed an AWG with 50 nm of spectrum range, and the resolution was 2.5 pm, but the accuracy was about 40 pm from the results [ 6 ]; Li studied an ultrasmall AWG system with 0.8 nm channel spacing with the interrogation performance not mentioned [ 7 ] and an AWG-based demodulation system [ 8 ] with a high precision of ±10 pm, yet it did not mention the dynamic range. However, it could be observed from the graphic results that the dynamic range is smaller than the channel spacing of 0.3 nm.…”

Here, we present a high-precision demodulation method that supports the arrayed waveguide grating (AWG) system, which includes a 1 × 8 AWG as the primary filter with a 0.5 nm channel spacing and a 1 × 4 AWG as the auxiliary filter with a 1 nm channel spacing. The high precision is achieved through an innovative method of decoupling three channels, involving two adjacent channels of the primary filter and one channel of the secondary auxiliary filter. Simulation results show that the AWGs have a good transmission spectrum with crosstalk below −24.8 dB, non-uniformities below 0.8 dB, insertion loss below −3.7 dB, 3 dB bandwidth of 0.25 nm, and 10 dB bandwidth of 0.43 nm. The interrogation precision can reach 8 pm, with a dynamic range of 0.4 nm, corresponding to a single FBG.

“…In DWDM optical networks, in order to upload/download the required signal wavelengths or to exchange the required signal wavelengths, this must be achieved by some common passive optical components, such as fiber Bragg grating (FBG), arrayed waveguide grating (AWG) [17][18][19], optical switches, optical circulators, and so on [20,21]. AWG is an important element commonly used to realize ROADM.…”

In this paper, we propose a new versatile routing device that utilizes arrayed waveguide gratings (AWGs), optical switches, and optical circulators to implement reconfigurable optical add/drop multiplexers (ROADMs), optical interleavers, and optical cross-connect (OXC). With the development of dense wavelength division multiplexing (DWDM) technology, ROADM and OXC technologies have also been put into practical use. Thus, the optical signal can be routed directly in the optical network according to its wavelength without the need for optical-electrical-optical (OEO) conversion. Although different optical network units (ONUs) have different bandwidth requirements, the use of optical interleavers has successfully solved the connection problem between old and new systems. According to the numerical experiments of static characteristics, the proposed routing device can effectively implement three different functionalities, thereby providing greater flexibility for fiber optic network applications.
