Actually there is no contradiction between us. The Pi
phase-shift is valid for a single reflection, while the Pi/2
phase-shift is obtained when adding all the parasitic
reflections to the first single reflection (when the
beamsplitter is made of parallel plates).<br>
One goal of the paper was to demonstrate that this global
achromatic Pi/2 phase-shift (admitted by QM) can fully be
explained by multi-interference theory, thus wave theory of
light. I think that it should be much more difficult by using a
particle model of light assuming indivisible photons.<br>

an 11-slide presentation. However,
it experimentally demonstrates that,
for Superposition Effect to emerge,
we must have the simultaneous
presence of two physical signals
carrying two physically different
phase information incident on the
opposite sides of the beam-combiner
of a two-beam Mach-Zehnder
interferometer. The superposition
effect emerges as purely a classical
effect facilitated by the dielectric
boundary of the beam combiner
(classical light-matter interaction;
no QM). The energies in the two
superposed beams can have any value,
no lower limit like “h-nu”. Thus,
single photon interference is
causally and physically an untenable
logic, in my view point.</span><o:p></o:p></p>

experiment also underscores that the
postulate of the “Wave-particle
duality”, is completely unnecessary
for EM waves. In fact, the
Copenhagen Interpretation becomes
more logical and causal without this
postulate. The QM formulation is
essentially correct. We do not need
to degrade it by imposing non-causal
postulates.</span><o:p></o:p></p>
