ABSTRACT
With the rapid development of the backbone network rates, there has been a gradual increase in channel spacing and bandwidth. The C&L band ultra-broad bandwidth array waveguide gratings (AWG) of 60-channel 100â
GHz channel spacing are designed and fabricated based on silica waveguide. A new parabolic design is used to achieve ultra-broad bandwidth and good spectrum. For the C band ultra-broad bandwidth AWG, the peak insertion loss, uniformity, 0.5â
dB bandwidth, 1â
dB bandwidth and 3â
dB bandwidth are 2.98â
dB, 0.36â
dB, 0.614â
nm, 0.721â
nm and 0.937â
nm, respectively. For the L band ultra-broad bandwidth AWG, the peak insertion loss, uniformity, 0.5â
dB bandwidth, 1â
dB bandwidth and 3â
dB bandwidth are 2.91â
dB, 0.27â
dB, 0.560â
nm, 0.665â
nm and 0.879â
nm, respectively. To ensure ultra-broad bandwidth AWG operation at different temperatures, a temperature control circuit is integrated into the packaging design. It has been observed that the performances remain virtually unchanged within the temperature range of -15 to 65 degree. The ultra-broadband AWGs have been successfully tested to transmit 96 Gbaud signals and can be applied to 600â
G/800â
G backbone network transmission. By using the C&L ultra-broad bandwidth AWGs of 60-channel 100â
GHz channel spacing, the total transmission speed over a single-mode fiber can reach 72Tbps/96Tbps.
