A ring laser gyroscope without lock-in phenomenon

Satoshi Sunada, Shuichi Tamura, Keizo Inagaki +1

We theoretically and numerically study the effect of backscattering on rotating ring lasers by employing the Maxwell-Bloch equations. We show that frequency shifts due to the Sagna…

Dependence of far-field characteristics on the number of lasing modes in stadium-shaped InGaAsP microlasers

Muhan Choi, Susumu Shinohara, Takahisa Harayama

We study spectral and far-field characteristics of lasing emission from stadium-shaped semiconductor (InGaAsP) microlasers. We demonstrate that the correspondence between a lasing…

Light emission patterns from stadium-shaped semiconductor microcavity lasers

Susumu Shinohara, Takehiro Fukushima, Takahisa Harayama

We study light emission patterns from stadium-shaped semiconductor (GaAs) microcavity lasers theoretically and experimentally. Performing systematic wave calculations for passive c…

Classical Phase Space Revealed by Coherent Light

Tomoko Tanaka, Martina Hentschel, Takehiro Fukushima +1

We study the far field characteristics of oval-resonator laser diodes made of an AlGaAs/GaAs quantum well. The resonator shapes are various oval geometries, thereby probing chaotic…

Wave Chaos in Rotating Optical Cavities

Takahisa Harayama, Satoshi Sunada, Tomohiro Miyasaka

It is shown that, even when the eigenmodes of an optical cavity are wave-chaotic, the frequency splitting due to the rotation of the cavity occurs and the frequency difference is p…

Sagnac effect in resonant microcavities

Satoshi Sunada, Takahisa Harayama

The Sagnac effect in two dimensional (2D) resonant microcavities is studied theoretically and numerically. The frequency shift due to the Sagnac effect occurs as a threshold phenom…

Ray-wave correspondence in the nonlinear description of stadium-cavity lasers

Susumu Shinohara, Takahisa Harayama, Hakan E. Tureci +1

We show that the solution of fully nonlinear lasing equations for stadium cavities exhibits a highly directional emission pattern. This directionality can be well explained by a ra…
