“…The designs and simulations are performed using WDM Phasar software [30], based on the beam propagation method (BPM). This method is especially adapted for the design of AWGs on HIC platforms [31,32], and several research groups utilized the WDM Phasar software in SOI-AWG designs [33,34]. It justifies its choice for simulations on the SOI platform with effective index approximation.…”

We present the design and simulations of a novel integrated device concept enabling a frequency conversion of a broad signal. The solution is based on a hybrid silicon–graphene photonic chip, which could be used for controlled spectrometry in low-cost devices. The device is based on a silicon-on-insulator (SOI) platform on which an arrayed waveguide grating (AWG) is designed for operation at the center wavelength of λ = 1800 nm. The AWG is spectrally separating one broad input signal to thirty-two-output channels with a channel spacing of 2.72 nm. The output signals are well separated and uniform with the extinction ratio and the standard deviation of 10.00 dB and 0.04, respectively. The 3 dB channel width is 1.34 nm, which is suitable for sensing applications with significant accuracy. After spacial and spectral separation, each output signal is then converted to one signal at 1480 nm wavelength through a graphene-based saturable absorber scheme. Therefore, the device allows the detection of each separated signal with a simple near-infrared camera on which the outputs are imaged using conventional optics, leading to a classical pixel/wavelength correspondence. Crossed-waveguide couplers are designed to combine the controlling signal at 1480 nm to each channel waveguide of the AWG. The combination of the signals saturates the graphene layer at the output waveguides, allowing the pass of the controlling wavelength. This device can be applied as a spectrometer in environmental sensing and monitoring with high efficiency and low cost.

“…This type of waveguide has been introduced to several integrated optical devices, including AWGs [9]. AWGs are demonstrated on a 4-µm-thick SOI rib waveguide with the integration of variable optical attenuators to equalize a multiwavelength source [10] - [11]. A 3-µm-thick SOI is used to design an ultrawide-band AWG which operates from Oto L-band.…”

32-channel arrayed waveguide grating spectrometer (AWG) at 1800 nm is demonstrated on a 2-µm-thick silicon-on-insulator (SOI) platform. The design and simulation of the device are performed using the beam propagation method (BPM) and we obtain the 3-dB channel width, channel spacing, and extinction ratio of 1.16 nm, 1.56 nm, and 5.17 dB, respectively. The AWG demultiplexer can be applied in the central part of a spectrometer which is replacing in integrated optics a prism or a grating in conventional free-space optics.

“…Arrayed waveguide gratings (AWGs) are key devices in dense wavelength‐division multiplexing system, in which they can serve as multiplexers [1–5]. Recently, many research groups have focused on the development of polymer AWG multiplexers and have fabricated some such optical devices using various polymeric materials [6–10].…”

An efficient technique is reported for reducing the spectral shift of the polymer arrayed waveguide grating. By regulating the spin‐coating rate to control the polymer core thickness, the spectral shift of the device can be reduced obviously. The designed value of the central wavelength is 1550.918 nm, and the measured central wavelength is 1550.911 nm. That is, by using the presented technique in the fabrication of the device, the spectral shift is reduced to 0.007 nm, which is much less than the wavelength spacing of 0.8 nm. © 2010 Wiley Periodicals, Inc.
