“…For example, the tolerance of wavelength dispersion and differential group delay (DGD) are approximately 2 ps/nm and less than 1 ps, respectively, for 160 Gbit/s transmission. Considering the temperature change of 40 degrees, it would change the chromatic dispersion of 80 km fibers by 6-7 ps/nm, and make adaptive dispersion as well as dispersion slope compensation [19,75,77,80] indispensable.…”

As the Internet data traffic increases explosively, the optical networks will evolve into "photonic networks", in which "wavelength" label is used to route largecapacity optical signals at optical path cross connect (OPXCs) nodes.[34] Further development of ultrafast all-optical processing technologies enables us to further upgrade the photonic networks into those with much more flexibility and higher transparency, where ultrafast optical signals of any bit rates (2.5, 10, 40, 100, 160 G/ch) and frame/modulation formats (GbE, 10 GbE, SDH, OTN/ NRZ, RZ, CS-RZ, RZ-DPSK, etc.) are processed and transmitted all-optically without optical-electrical-optical (O-E-O) conversion from end-to-end.

“…In this compensator, the slope of the GVD, as well as the GVD itself, are precisely controlled by a various temperature gradient induced by Peltier elements. 4 Several compact non-fiber-based dispersion compensators have been developed. One example is a dispersion compensator using a virtually imaged phased array ͑VIPA͒.…”

Two vertically coupled asymmetric InGaAsP ridge waveguides were fabricated and tested as a tunable dispersion compensator. In this waveguide, two coupled modes, symmetric and antisymmetric, exist simultaneously and have a significant amount of group-velocity dispersion (GVD), making it possible to reduce the size of the dispersion compensators. Since the GVD can be continuously controlled by changing the temperature of the asymmetric coupled waveguide, a semiconductor asymmetric coupled waveguide has great potential as a basis for a compact tunable dispersion compensator. To demonstrate tunable dispersion compensation, we carried out an experiment on the pulse compression of frequency-chirped pulses by using the InGaAsP asymmetric coupled waveguide at various temperatures of the waveguide. We observed a change in the compression ratio, ranging from 42.7% to 84.2%, as the temperature of the waveguide changed from 8to48.9°C. A theoretical study showed that the observed change in the compression ratio was well explained by a temperature tuning of the GVD of the coupled modes resulting from temperature-induced change in the refractive indices of the waveguide materials.
