Lance Glasser’s publications in refereed journals through the early 1990s

New kind of multiport memory. It exploits the fact that we store words rather than just bits in memories. By storing the words in clever ways one can tolerate collisions among accesses to the memory and still guarantee perfectly correct results. Prof. Ron Rivest of M.I.T. helped me with the concepts

The theoretical work of which I am most proud was on a linear circuit theory conservation theorem that produced tight bounds on the performance of circuits composed of linear elements. The basic paper using the numerical range was titled “Frequency limitations in circuits composed of linear devices.” I followed it by some work that built on that foundation, including “The stability and passivity of MOSFET device models that use nonreciprocal capacitive elements.” Prof. John Wyatt of M.I.T. was my coach and mentor for this whole set of activities.

Papers on multiprocessors and on wireless chips from the 1980s

I was a member of the team that demonstrated the first modelocked semiconductor laser. We did it first with GaAlAs and then with GaInAsP. These experiments generated pulses more than an order of magnitude shorter than anything previously achieved.
