Reduction of interchannel interference noise in a two-channel grating-based OCDMA system using a nonlinear optical loop mirror [PDF]
, 2001 We show that a nonlinear optical switch can be used to suppress the interchannel noise generated under multiuser operation within a coherent, direct-sequence optical code-division multiple-access (OCDMA) system.

Miniature nonlinear optical-loop mirrors with semiconductor optical amplifiers [PDF]
Technical Digest. Summaries of Papers Presented at the Conference on Lasers and Electro-Optics. Conference Edition. 1998 Technical Digest Series, Vol.6 (IEEE Cat. No.98CH36178), 1998 We present our experimental results of miniature nonlinear optical-loop mirrors made of GaAs-AlGaAs quantum-well optical amplifiers. The ridge-loading waveguide loop has a 300-/spl mu/m radius with a 4 /spl mu/m ridge width. The loop is connected to a multimode interference (MMI) waveguide.

Dissipative solitons in pattern-forming nonlinear optical systems : cavity solitons and feedback solitons [PDF]
, 2005 Many dissipative optical systems support patterns. Dissipative solitons are generally found where a pattern coexists with a stable unpatterned state. We consider such phenomena in driven optical cavities containing a nonlinear medium (cavity solitons ...
