comment Boson calculus and Maximum Weight State
Yes, we use commutators to shift $b_2$. In fact all the commutators are trivial and the operators commute because the raising operators do not contain $b_1$ which is the only operator not commuting with $b_1^{\dagger}$

comment Is the third spin vector of a photon always suppressed?
@WetSavannaAnimal aka Rod Vance Electromagnetic waves in waveguides propagate in TE and TM modes where either the magnetic the electric field have components along the direction of propagation.
