The case is one of several recent corruption trials to hit this Southeast Asian city-state, which has a reputation of cultivating a clean bureaucracy.
Tey Tsun Hang was fired from the National University of Singapore last week after being convicted of six counts of corruption involving what was described in court as "unbecoming" behaviour for a senior educator.
Chief District Judge Tan Siong Thye sentenced the 42-year-old to five months in jail and ordered him to pay a fine of 514 Singapore dollars (USD 408). He plans to appeal and is expected to be freed on bail while awaiting further hearings.
The student also told investigators that she had an abortion after becoming pregnant with Tey's child.

Tan criticised Tey at today's sentencing hearing, saying he had "clearly and systematically" taken advantage of a student and told a "litany of lies" after being discovered.
Tey, a former judge himself who received an annual salary of 225,000 Singapore dollars (USD 180,000) for his university job, had faced a maximum sentence of seven years and could have been fined 100,000 Singapore dollars (USD 79,000).
High-level corruption cases were once rare in Singapore, which has a well-paid, efficient bureaucracy. But a series of scandals has shocked Singaporeans this past year involving senior public officials accused of misconduct and obtaining sexual favours in exchange for furthering their business interests.
In the most recent other such court verdict in Singapore, former Civil Defence Force Commissioner Peter Lim was convicted of graft last week for corruptly obtaining oral sex.
