Abstract

Solitons on fibers are ideal for all optical switching operations.¹ Squeezed solitons promise to provide improved measurement capabilities.² The self-induced transparency (SIT) in CdS has been proposed as a particularly convenient means of squeezing.³ For this reason it is important to understand the quantization problem of solitons. Several authors have attacked the problem in the case of the nonlinear Schrodinger equation (NSE) both numerically⁴ and analytically.⁵ A particularly simple approach to quantization can be worked out in the limit of a linearized approximation. Since all switching and squeezing operations employ pulses with many photons (n > 10), the linearization is always legitimate.
