“…Our approach reduces optical system complications and costs and eliminates possible failures caused by electronics. Compared with the most recently reported athermal arrayed-waveguide-grating-based MUXs-DEMUXs 27,28 there were no extra loss and extra phase errors. We also demonstrated improved performance in terms of insertion loss and cross talk compared with results recently reported.…”

A high-density wavelength division demultiplexer (DEMUX) capable of demultiplexing eight-channel 200-GHz optically spaced signals into a 62.5-microm multimode-fiber array is reported. The wavelength range of operation is from 1549.32 to 1560.61 nm within the International Telecommunication Union grid. The measured wavelength accuracy is within 0.04 nm. The mean insertion loss of this DEMUX is 1.95 dB. Thermal analysis and temperature testing results are reported. The temperature test cycling from 20 degrees C to 60 degrees C indicates that the wavelength thermal drift is less than 0.8 pm/degrees C. Adjacent cross talk is measured to be better than -45 dB. The measured data transmission bit rate of this device is higher than 3.5 Gb/s.

“…14 The very high dn/dT value ͑Ϸ3ϫ10 Ϫ4 to 4ϫ10 Ϫ4 /°C͒ of the elastomeric silicone resins is also used for thermal compensation to eliminate the need of temperature control essential for stabilizing silica-based AWGs 16,[110][111][112] and reconfigurable OADMs 113 in practical applications. The absorption-related loss in materials for such applications is not a critical issue, because the polymer-inserted optical path is very short.…”

With fiber optical telecommunication systems penetrating into metropolitan and access networks, planar waveguide technology is increasingly being considered a solution to the bottleneck of cost-effective manufacture of passive components. Being recognized for their high thermo-optical coefficients, ease of fabrication, cost-effectiveness, and compatibility with other materials, polymers as a platform technology for waveguide devices are gaining more and more commercial acceptance. Fully exploiting the potentials of the polymeric materials demands comprehensive understanding of both the specific device applications and various polymer systems. The right choice of materials is often the key to the success of component development. Unfortunately, since extensive study of polymeric materials and devices operating at 1.55 m began just recently, few ideal materials have so far been made commercially available. From the polymer chemistry point of view, it is possible to tailor the materials to meet specific and strict requirements for optical waveguide devices. This is a review of the most promising fluorinated polymers and silicone resins and their demonstrated device applications. The paper is designed to provide a guide to both polymer scientists who want to develop novel high-performance materials for waveguide applications, and optical engineers who need to gain insight into the materials.

“…High passband center wavelength accuracy is important in an athermal AWG whose center wavelength cannot be tuned by controlling the temperature. Although some methods have been reported for tuning the center wavelength by adjusting the position at which the input optical fiber is connected [10] or by using a separate chip with an input waveguide [12], these methods also impose some restrictions on the circuit layout or complicate the assembly. To avoid these drawbacks, a technique for tuning the center wavelength by irradiating the arrayed waveguides with a UV laser has recently been developed [13].…”
