Theoretical Calculation of Beam Quality Factor M~2 of Stripe Semiconductor Lasers

Zhu Xiaopeng Wei Xin Ye Xiaojun Kang Xiangning Xu YunHou Shihua Sun Yongwei Chen Lianghui(National Engineering Research Center for Optoelectronic Devices, Institute of Semiconductors,The Chinese Academy of Sciences, Beijing 100083)(Received 29 October 2001; revised 11 March 2002)  
The M 2 factors, beam waists and far field divergence angles of the beams of two kinds real refractive index stripe waveguide semiconductor lasers, plane ridge waveguide and plane buried waveguide lasers, are investigated by means of nonparaxial vector moment theory and plane wave spectrum. The waveguide optical modes were obtained by a semi vectorial 2\|D waveguide model. The effects of waveguide structure parameters on M 2 facotor are discussed and the beam properties are compared between the two kinds of laser structures.
