We demonstrate that the emission spectrum from a quantum dot near the edge of a photonic band gap (PBG) can be
spectrally resolved on the subwavelength scale using coherent control. In the case of the coherent control, confined light
near a quantum dot embedded in photonic crystals can be released by changing the phase of the external laser phase,
without closing the PBG. Moreover, in this demonstration, we examine the spectrum resolution of the coherent control,
which indicates that the spectrum resolution is the subwavelength scale. Therefore, even if there are many quantum dots
are embedded in photonic crystals, we can be operated a quantum dot with a specific resonant frequency. This technique
may provide a basis for N-qubit operation for quantum computations and nanophotonic devices.
