A symmetric, multimode slab waveguide has a core width 2ρ, a uniform cladding index ncl and a linear, graded-index profile n(x) in the core that is continuous and symmetric about the z-axis. The variation in the x-direction is defined by
where nco is the maximum index on the z-axis, Δ is the relative index difference with the usual definition and the x-axis is orthogonal to the z-axis of symmetry of the waveguide.
(a) Substitute the above profile into the second-order differential equation as given in lectures and solve the equation to determine the curved bound ray paths for x as a function of z. Assume that all ray paths are periodic and start at x=z=0. The initial angle the ray path makes with the z-axis at x=0 is θz, i.e. dx/dz=tanθz at z=0.
(b) Sketch approximately the shape of a bound ray path along the waveguide.
(c) Use (a) to determine an expression for the bound ray half-period zp, i.e. the distance between successive crossing points on the z-axis.
(d) Determine the range of values of θz for all bound rays within the core, i.e. those ray paths that do not reach the core-cladding interface and therefore satisfy |x|<ρ.
In the following experiment, a constant-pressure calorimeter containing 100 ml of H 2 O is used. The initial temperature of the calorimeter is 24.6 o C. If 18.6 g of CaCl 2 is a
