Waveguides Support High Channel Count

A proprietary manufacturing technology based on semiconductor process techniques that etches optical circuits onto silicon is said to facilitate volume production of the company's arrayed waveguide gratings (AWGs). Two versions of the AWGs are available: Gaussian passband and flattened passband.
Both versions come with 16, 24, 32 or 40 channels and with channel spacing of 50, 100 or 200 GHz. The silica-on-silicon waveguides also offer very low crosstalk (<22 dB), polarization insensitivity, low insertion loss (Gaussian passband, ≤6.0 dB; flattened passband, ≤8.0 dB), and high channel-too-channel uniformity, making them well-suited for use in DWDM, long haul and metro applications.
