WaveSplitter displays planar lightguide circuit wafer and DWDM module transmitting 10 Gb/s signals

March 16, 2001
Mar. 16, 2001--At OFC next week in Anaheim, Calif., WaveSplitter Technologies, Inc., a worldwide supplier of fiber-optic components for optical amplifier and DWDM systems, will display what is believed to be the first 8-inch planar lightguide circuit (PLC) wafer. The company will also unveil a 25 GHz, 160 channel DWDM module transmitting 10 Gbits/second signals.

At OFC next week in Anaheim, Calif., WaveSplitter Technologies, Inc., a worldwide supplier of fiber-optic components for optical amplifier and DWDM systems, will display what is believed to be the first 8-inch planar lightguide circuit (PLC) wafer. The company will also unveil a 25 GHz, 160 channel DWDM module transmitting 10 Gbits/second signals.

WaveSplitter has broadened its product portfolio to include the planar lightguide circuit (PLC) technology platform to offer higher optical functionality and integration to meet customers' application needs.

This technology enables multiple, complex optical functions to be combined on a single wafer and a higher level of integration, resulting in a cost reduction for system designers. The 8-inch wafer size is the largest silicon wafer currently being utilized in the fiber optics industry and offers more than 2.5 times the surface area of the industry standard 5-inch silicon wafer, yielding many more devices per wafer and enabling system designers more real estate on the wafer in which to integrate multiple functions.

Planar lightguide circuits are a key technology to enable the optical component industry to address the opportunity presented by the growth in bandwidth demand. WaveSplitter's PLC technology platform offers the benefits of wafer-scale processing, automation, integration of multiple functions and customization to individual system requirements. Lower costs can be achieved through high-volume wafer-scale processing while allowing integration of multiple functions on a single substrate to increase functionality with a reduced footprint. WaveArray High Channel Count AWG and custom PLC circuits are the first products to be introduced by WaveSplitter with units already shipping to customers.

Also at OFC, WaveSplitter will unveil a 25 GHz, 160 channel DWDM module transmitting 10 Gbits/second signals. The demonstration will highlight excellent flat top passband and dispersion performance required for very high data rates through dense channel spacing. This combination of dense channel spacing and very high data rate signal addresses the need of DWDM system integrators to reduce the cost of higher bandwidth solutions by packing more channels into the available bandwidth while simultaneously increasing transmission speed.

This demonstration is based on the integration of a 1x4 25 GHz WaveProcessor Interleaver with four forty-channel, 100 GHz WaveArray array waveguide gratings (AWGs) to create a complete 160 channel demultiplexing solution contained within the standard C-band wavelength range running at 10 Gbits/second transmission speed. It will be running live during the OFC trade show at WaveSplitter's booth # 2458.

An eye diagram shows the optical performance obtained through the demultiplexer. The WaveProcessor Interleaver offers an excellent flat top passband and dispersion characteristics needed at high data rates of 10 Gbits/second. These specifications are critical as system integrators strive to improve spectral efficiency by running high bit rates through dense channel spacing.

The combination of a WaveProcessor Interleaver with WaveSplitter's WaveArray AWGs enables a complete high-bandwidth solution. The WaveProcessor Interleaver allows very dense filtering with low insertion loss, a flat passband, and excellent crosstalk. WaveSplitter's AWGs are excellent for filtering high channel counts in an efficient manner.
