Mike Wiemer


Mike Wiemer defended his Stanford University Ph.D. thesis, "Monolithically Integrated Long Vertical Cavity Surface Emitting Lasers," in March 2007. Long Vertical Cavity Surface Emitting Lasers (LVCSELs) are a new class of surface emitting laser which can in principle be mode-locked. Mode-locked lasers put out short pulses of light at precise repetition rates.  They can be used in short distance data interconnect systems in a variety of ways. For more on his work on LVCSELs, mode-locking, and other topics, see the "Projects" tab. 

He is currently writing and thinking about what to do next.

Among his interests is a desire to change the cost structure and integration scale of optical devices by moving photonics into the silicon material system. In his view, this will enable photonic interconnect systems to be used in computing. Ultimately, only by moving optics closer to the microprocessor can the computing industry solve its looming data interconnect problem, and the photonic industry find a volume application to drive future revenue.

Aside from pure technical interests, he is also interested in technical business development.

Chirped Mirrors for Optical Pulse Compression
Tuesday, 10 April 2007
Here I discuss the design of double chirped, AR coated mirrors for dispersion compensation in mode-locked lasers. I explore the various design parameters (including material choice) and catalog their effect on the dispersion characteristics. The major problem in chirped mirror design is impedance matching the ambient medium to the stack. Non-ideal impedance matching results in undesired oscillations in the dispersion vs. wavelength curve of the mirror. I use a transfer matrix formalism for calculations.

Finding Resonator Modes & Losses
Tuesday, 10 April 2007
 Fox-Li Resonator Simulations:

Here I discuss how to code up a simulator which can find the modes and associated losses of an arbitrary optical resonator. The simulator can handle resonators with arbitrary curved surfaces, roughness, and apertures. I use the method created by Fox and Li.
