Zusammenfassung:A laser-based molecular sequencing system includes a two-dimensional photonic crystal surface emitting laser (PCSEL) array including a plurality of PCSEL devices located in a first layer, each PCSEL device oriented in a direction perpendicular to the first layer. The system also includes a controller configured to modulate a bias on at least one PCSEL device of the plurality of PCSEL devices, the modulation configured to selectively operate each PCSEL device as an emitter or detector at a point in time based on the bias.
