Bandwidth-enhanced volume grating for dense wavelength-division multiplexer using a phase-compensation scheme
2005
Applied Physics Letters
A phase-compensation scheme is proposed and demonstrated to overcome the intrinsic tradeoff between the dispersion and the bandwidth of a volume grating. Its application to a volume grating-based dense wavelength-division multiplexing ͑DWDM͒ device is explored. A DWDM device is fabricated by using a 45°/82°configuration. To achieve phase compensation of the Bragg condition, a wavelength-dependent incident angle for a dispersion-enhanced holographic grating at 82°is generated through a prestaged
