In 1961 they published the first carrier will be injected into the semiconductor PN junction to achieve the "injection laser" exposition and demonstration in the tunnel diodes as high as in Jane and the PN junction to achieve population inversion (which is Produced by stimulated emission of the necessary conditions for) the possibility, but also that active high-density areas around the most active carrier of the border areas on both sides of the refractive index of a difference, creating optical waveguide effect.

他们又于1961年最先公开发表将载流子注入半导体PN结以实现"注入激光器"的论述，并论证了在如隧道二极管中那样高度简并的PN结中实现粒子数反转(这是产生受激发射的必要条件)的可能性，而且还认为有源区周围高密度的多数载流子造成有源区边界两边的折射率有一差值，因而产生光波导效应。
