英文摘要 | PURPOSE:To produce a lateral junction stripe (TJS) laser which is of proper lateral beam angle and of lower thershold current by maintaining the carrier density of an n type region at 4X10/cm-1X10/cm. CONSTITUTION:An active region is located between p type and n type regions so that lateral beam angles of a TJS laser is determined by refractive indexes of the active region 10, p type region 6 and n type region 7. Increase in difference between the refractive index values of the active and n type regions by decreasing the refractive index of the n type region results in widening of the beam angle. As shown in the figure, the higher carrier density, the smaller refractive index of the n type region at its carrier density of 5X10/cm or more so that the higher carrier density of the n type region, the wider lateral beam angle. In this actual instance, the beam angle of 17 deg. can be obtained at the carrier density of the n type region at 4X10/cm-1X10/cm. Moreover, another advantage from widening of the carrier density of the n type region is that value of the threshold current becomes lower. |
