Agile and Upgradeable Multi-wavelength Source for Dense Wavelength Division Multiplexing Networks
LEOS 2007 - IEEE Lasers and Electro-Optics Society Annual Meeting Conference Proceedings, 2007 We demonstrate a multi-wavelength source covering the whole C-band with 100 GHz or 50 GHz spacing on the ITU-T grid. Error-free operation of the modulated channels is obtained with identical performance to commercial DFB lasers.

All-fiber dense wavelength division multiplexers
SPIE Proceedings, 1994Fused and tapered single-mode fiber couplers are used to make polarization insensitive Wavelength Division Multiplexers with a wavelength spacing of around 1 nm. Different structures are presented. As opposed to that of single highly elongated fused couplers, their responses are polarization independent.

Wavelength-stabilized Laser Source For Dense Wavelength-division Multiplexing
CLEO '97., Summaries of Papers Presented at the Conference on Lasers and Electro-Optics, 2005Dense wavelength-division multiplexing (WDM.) systems with channel spacings of 100 GHz require laser sources with wavelength stability better than 10 Ghz over a 20-year useful equipment life.

Photonic instantaneous frequency measurement using a dense wavelength-division multiplexer
Applied Optics, 2021A photonic instantaneous frequency measurement receiver based on frequency to optical power mapping is proposed and experimentally demonstrated. One channel of a dense wavelength-division multiplexer (DWDM) is used as an optical filter to establish a power ratio function related to the frequency of the microwave signal.

Dense Wavelength Division Multiplexer based on Microring Resonators
2018 IEEE Student Conference on Research and Development (SCOReD), 2018This paper demonstrates a dense wavelength division multiplexer (DWDM) based on microring resonators using ring radius variation method. In this design, the spacing between each channel was kept constant at 0.8nm throughout the S, C and L bands. The reference ring size of the ring resonator was 1um.

Dense wavelength division multiplexing radio-on-fiber systems
MWP 2003 Proceedings. International Topical Meeting on Microwave Photonics, 2003., 2005Dense wavelength division multiplexing (DWDM) millimeter-wave radio-on-fiber (ROF) systems are presented, in which we will focus on its multiplexing and demultiplexing techniques and photonic frequency conversions. The 25 GHz-spacing, 60 GHz-band DWDM ROF is experimentally demonstrated.

A novel architecture for dense wavelength‐division multiplexing/subcarrier multiplexing networks
Microwave and Optical Technology Letters, 2001AbstractWe propose and demonstrate a new survivable dense wavelength‐division multiplexing/subcarrier multiplexing (DWDM/SCM) network based on the star–bus–ring architecture (SBRA). This architecture ensures an OBI‐free optical network, and can serve tremendous subscribers. In addition, remote nodes and bidirectional wavelength add/drop multiplexers (B–

Sparsely-Filled Densely-Wavelength-Division-Multiplexed Networks
Photonics in Switching, 1993It has been clear for some time that optical fibre transmission systems have the potential to carry vastly greater amounts of traffic than they are currently used for. For example, in Fig.1, we show typical values for the insertion loss of a 50km fibre section in the 1500nm window and overlay it with an approximate representation of an Erbium Doped ...

Multi-Wavelength Laser Source for Dense Wavelength Division Multiplexing Networks
OFC/NFOEC 2007 - 2007 Conference on Optical Fiber Communication and the National Fiber Optic Engineers Conference, 2007We propose and demonstrate an ITU-T grid compatible DWDM laser source with 50 GHz channel spacing. It consists of a passively mode-locked laser, supercontinuum-generating photonic crystal fiber and fiber Fabry-Perot filter for spectral selection.
