Modulated photon confined states with graded-index photonic quantum well structure;

The transmission properties of 1D symmetrical photonic quantum-well in the form(AB)_m(ABBA)_n(BA)_m were studied in detail,including:1.

The transmission properties of 1D symmetrical photonic quantum-well in the form(AB)m(ABBA)n(BA)mare studied with transmission matrix method(TMM).

5(ωa/2πc),when the transmission band of photonic crystal(CD)n is completely inside the band gap of photonic crystal(AB)m(BA)m,both sharing the same central frequency as their symmetry centers,mirror symmetrical photonic quantum well is formed.

When the transmission band of photonic crystal CD is completely inside the band gap of photonic crystal(AB)m(BA)m,both sharing the same central frequency as their symmetry centers,mirror symmetrical photonic quantum well is formed.

This paper deduces the formula of the multi—quantum well laser s optimal well numbers.

The cross-saturation characteristics of GaN quantum well lasers are theoretically calculated and analyzed based on the analyses of the energy band structure and the transition matrix elements of GaN.

In this paper,the current modulation characteristics of a high power GaAs/GaAlAs quantum well laser in low frequencies(100Hz～20KHz)were experimentally investigaed in the first time.

Study on the chaotic synchronization communication of different structure SCH quantum well lasers;

At the same time,a multi-quantum well laser is used as laser LED,which makes the carrier frequency have a wide range(0~20 MHz),and so enhances the frequency bandwidth and dynamical range of PGC demodulation.
