We present a simple technique to generate arrays of optical traps with different trapping forces. The arrays can be configured in two or three dimensions (2D, 3D) by means of phase diffractive optical elements (DOEs) displayed on a phase programmable modulator. DOEs design is based on the approach of spherical wave propagation and superposition, which enables to individually control the strength of the optical trap. Experimental results using silica beads trapped with different forces in 2D and 3D configurations are presented.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
